Thanks for the help! I actually use a tablet for drawing and for the Ctrl + Z I don’t need to press Ctrl, so maybe it’s just a problem with the tablet in wich sometimes accidentaly reads Ctrl + Z as just Ctrl?
I don’t know, but I will just wait for customisable shortcuts to fix my problem, when they arrive.
Again, thanks a lot! I really love your program and I will 100% buy it when it’s complete.
