Double LMB click works wrong

[ddfun]

Hello.
May be somebody met this problem - if I do double left mouse click then character window opens.
And one more problem. I can't put item to the stash. If I try to drop item then character window opens again and item still got stuck to cursor

My OS - win10. Belzebub is installed to GOG version

Thanks in advance
