How to stop "Update in progress" in supervisor?

Hi,

I have a problem opening big files. If I try to open folder containing big files, there is a text "Update in progress" in the supervisor which goes on and on and on. Then eventually it might show contents of the folder briefly and starts to update again and you have couple of seconds to open the file that you want. This is very annoying problem and occured first time in version 2 years ago (maybe).

There is a one way to open large files faster by opening a new project but that is not very convient either.

Is there some way to get rid of the infinite updating of the supervisor?
