I'm using version 1.4.6 and have tried playing around with the Display options, but can not get the Windows mouse pointer to hide away. It hides away on my desktop pc, so it may be an issue with the screen resolution on the EEE.
I will try playing around with the screen options on the EEE PC to see if I can get it to work, cheers.
To answer the other question, WinUAE runs pretty well on the Asus EEE PC. Obviously it's not as fast as running on a powerful desktop, but it's acceptable for my needs :-) The default sound settings don't seem to work for me though, I get muffled and broken sound coming through. I haven't tried playing around with the sound options yet, but I think it should be fixable. Apart from the Windows mouse pointer issue above, I am quite happy with the performance :-)
Thanks
