Sorry for making a new topic, but I think this is a different subject altogether.

You see, I just tried running Jazz Jackrabbit in DOSBox on my Windows XP virtual machine on my Mac, and it ran perfectly fine, except for one thing: Jumping is very unresponsive. I can only jump when I first hold down alt (jump key) and then press a direction key. Which is kind of annoying.

I also have the same issue with Jazz Jackrabbit 2 (again on my Windows XP VM), except it's even worse because it only seems to jump when it feels like it.

Has an issue like this ever been reported, or is there a solution? It's a really weird problem. Jazz 1 is playable (if I get accustomed to the weird jumping thing), but Jazz 2 is pretty much impossible.
