On OSX 10.4.11 PPC
1. start up the program
2. click on 'presets' icon
3. nothing appear, cannot draw or click on menu bar
4. hit ENTER, come back to normal
5. View -> Reset all panel scales
6. click 'presets' icon again, now it works
this happens most time starting up.
another thing is brush size type box
1. click lower left corner (percentage thingy)
2. nothing appear, need to hit ENTER to get out
does this happen in purchased version?
