30 days with Amiga Os4.1 - Day 2

Today i decided to make some drawing with my os4.1 box.
Amiga was famous for its graphical capabilities so i thought it could be a good starting point to draw something.
I went on osdepot and i find lodepaint. I know it under aros and it's a good pixel drawing program.
I downloaded it but when i launch it, the screen totally corrupts and i rebooted several times.
No way.
Strange: i found no issues about this in amiga forum. Could be it needs some libraries?
I downloaded letsplay. It's a child colour game.
I plugged my wacom bamboo graphical usb tablet and it works!
Yes. My 4 years old child started to play with it, and it works very well.
