Undo not working

Having trouble with LMMS? Ask about it here.
Hello,

The Undo-Button is not working. It doesn't make anything undone.

Version: "0.4.5 (Win32/i386, Qt 4.5.2, GCC 4.4.2 20090806 (prerelease) mingw 20090616"

My System: Windows 7 Prof. 32 Bit, Intel T5750

Any Ideas what could possibly be wrong with my lappy? Or even better: Can someone guess a solution?

Would be totally awesome if someone could provide an idea^^

regards

tuelle
There is nothing wrong with your lappy.. Undo is pretty much dysfunctional at the moment :/. I guess LMMS needs more developers.. *hint to self* ;]
