Now the question is: what's causing it. Source could be from the virtual machine or the kernel. I guess I'll have to start doing my work from a virtual floppy and see if I can experience the same problems in QEMU. I'll take this as an excuse to experiment with writing a game I've been thinking of. You throw the first version away, anyway— so I guess it's not a big deal if I lose my work. :-) Sounds like you find the issue before too long on VirtualBox. If I can't reproduce the problem on QEMU with a virtual floppy, after several hours of work, then I'd look suspiciously towards VirtualBox.
