My buttons are grouped already in rows and columns. The state of every button 
(indicated by its colour) depend on state of other buttons (very complicated 
algorithm). So it is wery helpful to see all buttons at ones in order to hold 
situation under control.
I know now the amount of buttons does not matter for my problem. Something is 
wrong with buttons themselfs. For example I use system DC for buttons drawing 
and change font size and colour. Can I spoil something and call 
unintentionally the screen repaint?
