we encounter problems with tests executed in a test list. For some unknown reason the application crashes sometimes when the execution of a test list ends. A window to "Save/Restart", "Save" or "Exit" Test Studio is displayed. I attached the exception from the log file. Maybe the issue is related with our high result count (which is 851).

Hello Aaron,

Yes it seems that you are experiencing this issue due to the large number of results you have, as it can be seen from the log provided:

[06.26 10:18:31,Telerik.TestStudio.exe(356:1),Uncategorized] MainWindow.LogMessage() : Loading '851' results..

In order to overcome this issue please move the results in another folder and empty the current one, this way you will have your old results for further references and most probably you will not experience the problem
