mouse pointer problems driving me bonkers

["Michael Litchard" <michael%schmong.org@localhost>]

I've got an hvm netbsd instance. When I start X, I find that the two
pointers (the hvm pointer, and the 'outside' pointer)
don't stay very close together. What will happen, is that the hvm
pointer can't move to certain parts of the window
based on where the 'other' pointer is. If I move to the right, and the
other pointer reaches the edge of the window, the hvm pointer will
stop, and I have to fidget with it, to get it to go where I want it to
go.
Is there a fix, or workaround? If not, is there a way I can help fix this?
Here's my cfg file.
