And while you're at it, ask him to port his emulator to a real operating system. Windows doesn't count as an OS. It's pure crap and having the best Amiga emulator running on the worst OS ever is just painful and sad.
Don't do that. Toni will ignore you. ;-) (And despite Linux being free and Mac OS X being readily available, the market still says Windows is the best operating system. Funny that.)
EDIT: And to stay on topic, be specific in your bug reports. Toni responds very quickly to detailed, intelligent bug reports. Not so much to "it's broken."
