MuLAB 10.2.37 - strange behavior

[taxiboy]

I do install MuLAB 10.2.37, activated with my data. Now I do EXIT the App, it ask me if i want to save my session. I klick no saving. The App is closed (no running). Now my Recycle Bin is full of MuLAB data (it was empty before). MuLAB 10.0.85 does not have this strange behavior. This is a BUG in version 10.2.37.

Now my Recycle Bin is full of MuLAB data (it was empty before).
