Mouse:
You need to have a mouse driver loaded in DOS for it to work, usually called
MOUSE.COM or similar.  Unfortunately they can be hard to find with the
advent of Windows.

File-finding:
It may have something to do with LFN support -- try looking in the FAQ about
it, I don't know exactly what the problem might be, but I suspect you might
have to set a flag somewhere before using findfirst() etc.
