I'm sorry it was a typo. I was talking about
paint method above.
So when I open my app it looks like this (everything is transparent):
And I must move my mouse cursor above each button to show them.
No labels and panels are available either. However on my other PC with WinXP labels and panels are shown after moving cursor above the button. I really have no idea why this happens :/
Without paint method menu looks fine and app starts ok but when I add paint method it start to be messed up :/
