I use Office365 and my previewing works fine, BUT I also install an old disk-based copy of Office 2007 every time I buy a new computer.
Studio marketing... I get the impression that the marketers' tales are not reviewed by anyone who really knows the software and its limitations. I have not examined the marketing material from each release, but when I have, there have always been things that weren't quite right.

If your preview is Office 2007-based, then it's sure going to work, and work great - like it used to with my previous Studio 2011 (good ol' days...). Parallel installation of Office 2007 was one of the first things I tried upon encountering problems with preview in Studio 2017, but this caused many problems with Windows not exactly knowing which Office to default to etc. I even contacted Microsoft Support on this, but they said Office 2007 is not supported anymore (which is excusable after 12 years), so they can't help.

Just tried HTML preview and - nope, still the same crap. Will have to wait another 10 years apparently.

Have you seen a new release for 2019 since your last post?  Wondering why you think it would have magically changed?

I can tell you that we are going to remove the embedded preview altogether because we are not going to be able to improve it at all.  The hooks we used to have with earlier versions of Office are simply not there and we can't do anything with it.  So in the future the external preview in Word, and the html preview will be the only ones we will support.

I for one am glad about this because at least we can focus on improving something we have control over.  But the improvements that you are probably looking are not there yet.

Well, you don't mention the preview issues (nor do you mention the possible fixes, I presume?) in release notes, do you? And there have been some updates over the last 10 months, so POTENTIALLY there could have been some fixes.

I'm not even discussing the embedded preview at all anymore, I'm only referring to the HTML one, and it's just as unreliable as before, although at present it at least highlights your location in the document - when it works. Either way, since you have admitted the improvements are not there yet, all we can do at this point is wait and hope.

Just tried the HTML preview again. The highlight feature "hijacks" (!) the cursor from the text box, making you have to click on the text in Editor again and again if you want to have usable preview. This is completely pathetic and a behaviour I remember from over a year ago. This goes to show you guys aren't doing absolutely anything (or are failing at effectively doing anything) to rectify the erratic behavior of this important feature. To make things worse, the disappearing cursor doesn't repair itself after turning off the preview - you have to reopen the project/restart Studio!

It is logged as CRQ-6669 (so you know what to refer to in future if we have not addressed this with the next update).  It was created in 2017, so you're right in that this has never been addressed.  Looking at the comments I can see it's been scheduled to be addressed many times but always fell out when time got tight.

So we have failed to address this, no getting around that, but it seems to be planned into the next sprint so I hope there will be a release soon with this fix in it.

Ok Paul, thanks for a straightforward response.

Has anything been done regarding the preview thing in 2021?

Adrian Komiński

I just checked the CRQ and confirm this has still not been successfully addressed.  There has been a lot of activity in the bug thread and time spent attempting to address it but each "solution" seems to cause more problems in other ways.

The final comment from product management was this:

"For those watching this CRQ - as sometimes happens, it seems we are unable to address this within the engineering teams at this point. So we need to remove the fix version for now. There is potential light at the end of the tunnel however. Microsoft have released a new web view component called WebView2 that is based on Edge and that we might be able to use in Studio down the line. This would then replace the current IE11-based control. Obviously this is a longer term initiative but I thought I'd share this info here. We will investigate this component down the line and then take things from there. See https://docs.microsoft.com/en-us/microsoft-edge/webview2/ for more info on the control. "

This planned fix isn't a small piece of work and given the number of users affected it hasn't made it into a release yet I'm afraid.  I also don't have enough information to tell you when it might do but I'll raise this again.

Thx Paul. Does the above cover the HTML preview also or the Word previews only?

Yes.

I did get an idea from Daniel Brockmann which might help with this.  Have you tried using Ctrl+0 which can bring the focus/cursor to the Editor?  I know it's not ideal but it might be faster than using the mouse?
