There was freeze of UI, so I restarted my SQ4 beta4.
but new instance of SQ4 is terminated suddenly.
I tried to restart it by double clicking its shortcut, but the link was broken because its destination file "StrategyQuant4.exe" was removed.
I copied backuped "StrategyQuant4.exe" file into original folder, and then I can run SQ4.
But during writing this, I met one more case for this.. executable file was deleted once more.
I don't know what is the problem.
I deleted more than 3000 strategies from the databank of retester before this problem.
I think this might be somewhat related into this problem.

We'll check what could be the problem, but I suspect some other program is deleting the exe.
I checked the history of anti-virus software(kaspersky internet security), but no entry was found related to SQ4.
