Yes, i loaded up your WODTEST3.TOS and it tells me the following:

*****
Ramsize: 1.5 Megabytes
Work-Ram: 1204112 Bytes
Sync Mode: 60 Hz
SFX Mode: PSG Digital

This is a Blitter Machine!
Blitter Status: On
F1 to switch Sync Mode
F2 to change SFX Mode
F3 to (De)Select Blitter
*****

I am using a VGA Monitor to play my games.
I hope that helped you!

Cheers for your help, CJ! :)


*EDIT* Just tried your WODTEST1.TOS and deselected the Blitter and voila! It works fine. With Amiga-Music enabled! I just finished Level 1 for a test. So the Problem must be the Blitter it seems.
