Question

"Index out of range. Must be non-negative and less than the size of the collection." error message appears, when I enter a segment for translation. 
 This has happened many times i Studio 2015, and I have upgraded to Studio 2017, and the error persists. 
 The text here is in Danish, but it is the same as above.

This is very annoying, but what is worse, is that I can't use the shortcut Ctrl + 1 to insert the hits from Translation Results. 
 The only way to get the program to act normally again, is to close Trados Studio completely and start up once again. 
 Is there any explanation to this problem?

There are plans to do this, but I don't know the timescales on it. The best solution to speed and overall performance is a good SSD drive. I noticed a huge improvement when I switched to this kind of hardware and people like Jerzy Czopik or Walter Blaser who know a thing or two about hardware will probably say the same. I'm sure a 64-bit build would be beneficial, but you can make a big difference today. I also have 16Gb RAM and where this does help is being able to simultaneously run multiple applications without having to share the memory... but for Studio alone the SSD makes the most difference.

Hi Søren Vedel , 
 
There are a few KB articles on this problem here: 
 
 gateway.sdl.com/CommunitySearchResults 
 
But I'm not sure any of them apply to you based on your description so far. But take a look... you never know. 
 
In the meantime can you also share the full error stack with us? So not just a screenshot of the error message. Click on the little disk symbol and this will allow you to save the xml stack. Save it to your desktop and then post it as a file in here. 
 
Regards

Hi Søren Vedel ,

I removed your error messages and replaced them with a copy of the stack trace saved as an xml file. Note the difference... takes up less space. it's easier to read, and we can copy paste the text. Probably easier for you to add too! All you need do is save the message by clicking on the blue disk symbol and then attach the file you get to your post. The forum automatically renders it like this.

I'm not a developer, but the message seems to be pointing to a problem with your TM windows so if you have not tried this yet can you first try a simple View -> Reset Window Layout.

If that doesn't help can you try a reset? Rename this folder (just add _old to the end or something, it's not important what you rename it to) and restart Studio:

c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\14.0.0.0

 My laptop is quite new with 16 GB of RAM, and I never even get close to use 50% of them. 
 Surely this is another issue, that I maybe should open in another thread. 
 
 Not really. Studio is a 32-bit application so it can't use more than 2-3 Gb RAM.

Unknown said: What you should know, is that I frequently work with 5-7 TM's - rather big ones - and it seems as if Studio doesn't handle them very well. 
 Are these all installed locally or on an external drive? What kind of hard drive are you using... is it SSD?
