The problem is that is really hard to do. Especially in a cross platform
manner.

I couldn't figure out how to scale it for full screen, but that was my original
plan. Another benefit of scaling is that you can resize the window without harm:
if the text is too small to read then just make the window bigger.

I think I know what you're talking about. I had this problem with my gtk code
as well. This is because the host and guest pointers are not 'sync'ed, so when
the host mouse hits the edge of the screen, the guest pointer also halts (even
if it's not at the edge). GTK provides no way to fix this - basically you need
to test when the pointer is at the edge and warp it to the opposite side. But
this requires platform specific code (however I did write up the X and Windows
versions).

The cause of the problem becomes quite obvious if you don't make the host
pointer invisible when you grab the mouse.
