I tested with a 23 GB library and the dialog still worked fine to add a file from the library. Can you please send me mobilesheets.db at C:\Users\<your username>\AppData\Local\Packages\41730Zubersoft.MobileSheets_ys1c8ct2g6ypr\LocalState? That should help me reproduce the issue you saw. I have a fix in place for the other I mentioned (which may fix the problems you are seeing). It does seem to take an exceptionally long time to clean up resources after closing the dialog if you have a very large library though. I'll see if I can optimize that.
Thanks,
Mike
UPDATE:
I fixed the issue with closing the dialog with a large library. That's probably just what you were seeing - if you wait long enough, then it starts responding again. This will be fixed with the next update. All these issues are Windows only.
