Perform a "Reset window layout".

Unfortunately, it doesn't help. The same strange behaviour remains.

Indeed - I can confirm this strange behavior. In my case the Advanced tab is only partially visible with any kind of segment. However, when I click in another segment, for less than a second more buttons appear on this tab.

Actually, a fellow translator called my attention to this problem. She is a user of the old Word-based Trados. Now she has to use Trados Studio for the first time and is quite disappointed about this bug, which was reported over 3 years ago, in Studio 2015 too, as I can see in previous posts. Very sad news...

Which particular part of this Advanced tab are you missing so dearly? I would consider myself a power-user of Studio and use this tab maybe 3 times a year...

To be frank, I'm also a power-user of Studio but I have not used Insert symbol yet.  But my fellow translator wanted to use it right at the beginning.

Adapt ribbon - add a new group to Home tab and add the "Insert symbol" menu there.
However, I add most symbols via ALT+xxxx code, is much faster...

Hi Sandor Juhasz

Sorry, I wish I had better news for you ...

I complained about exactly this problem many, many years ago. It persisted from one version of Studio to the next.

The only "solution" I ever found was to get a new computer, new hard drive, new Windows 10 installation, completely new Studio installation, including creating everything from scratch: a new profile, new project templates, etc.

But even this was just a temporary reprieve, as the problem has returned since then.

I imagine that more people would comment here if they were having the same problem, so the echoing silence suggests that you and I are in a very small minority -- which means I wouldn't hold my breath waiting for a solution.

Or it might be that most users haven't noticed anything useful under the Advanced tab ;-)

That might sound silly, but I first noticed this problem when someone mentioned the Insert Symbol ribbon -- and I couldn't find it.

I had looked at the Advanced tab before but didn't see anything interesting -- because the Insert Symbol ribbon was missing!

I eventually figured out how to make the Insert Symbol ribbon appear again, but it is too time consuming a process.

This is how to make the ribbon appear again: If the cursor is in an Untranslated segment and the ribbon is not visible, then type something, anything, to change the segment to Draft status. Then move the cursor out of the segment. Then move the cursor back into the segment. Repeat this process every time you go to an Untranslated segment and need a special character.

Doing that quickly became tiresome, however, so I got into the habit of switching to Microsoft Word (I generally have a Word window open) and getting the symbol there. Fast, easy, reliable and familiar. And the Symbol window that pops up in Word is much faster and easier to use than the popup window in Studio.

As a result, the Advanced tab became just one more of the Studio "bells and whistles" that I don't use.

Hi Bruce,

How disappointing, indeed.

My fellow translator who is just trying to use Studio for the first time told me she cannot understand why Studio is crashing/shutting down frequently without any error message. I told her there might be some problem with that specific Word file.  :) I recommended using Ctrl + S (Save) frequently. This is the most important shortcut when I use Studio...

She told me she cannot comprehend how a program can crash so often. No other programs ever crash at all.

But Trados Studio does. I can also confirm.

Studio 2021 is around the corner, and even basic bugs and shortcomings have not been corrected for years.

I actually like Studio, in spite of the problems.

My comment about the bug was more informational: "The bug has been around forever. Don't expect anything soon!"

And it lets SDL know how to reproducibly Hide/Reveal the Insert Symbol ribbon -- although I think this particular bug will be with us until the user interface is rewritten.
