Hi All,
An update from our side:
1. We have received positive feedback about combinations Win7 + IE9/IE10
2. Win7/Win8 + IE11 seems to be the problem
3. It seems like CDT (or browser) is not really crashing. When the issue happens you can see high CPU peak and after a while the action is finished (for example directory search or number insert)
This is most probably caused by slow javascript execution but we cannot say for sure yet.
Testing continues!
Regards,
Jukka
