Hi there,
After an upgrade or new SR release, it will help if you perform a Windows Repair of Studio via Control Panel > Programs...
If this doesn't help, I have a group of things that I do if Studio is slow or crashes. Even if you have no speed or stability problems normally, they can happen with a big/old/complex project. Here's what works for me:
1) Go to File > Options > Editor > Automation then UNtick 'Enable LookAhead' under 'Translation Memory' and UNtick 'Enable verification of segment' under 'After Confirming Segments Manually'
Both these options should help speed things up. You can then verify the file after you've finished working on it all in one go via the Review tab > Verify or by clicking F8.
Then, in the Project Settings (or via File>Options if you create your own projects or work via Translate Single File), turn OFF upLift Match Repair.
Turning this setting off seems to help with files that for some reason cause Studio to crash. I am sure it helps with speed too.
If you want to know what any setting means under File > Options or under Project Settings, click the Help button bottom right of the settings window.
Keeping the above settings turned on if you need them works fine if you have a hi-spec fast computer and an excellent broadband connection. However, in less than perfect scenarios, it can help to turn one or all of them off.
I always have them all turned off unless I need them, and Studio works well for me...
I hope this helps,
All the best,
Ali
