I'd have to take issue with this in favour of the original poster who mentioned that moving the pointer in a circle is erratic. This is indeed true and well spotted - I only noticed it when I tried it last night. The normal use of the mouse produces excellent response and accuracy - we could do with more hardware cursors. It doesn't matter what speed you move the mouse, you get a very wierd circle. I tried this on my (company) HP workstation to make sure that it wasn't my lack of ability that was causing this - I could draw perfect circles. It's almost as if there is software which tries to anticipate that you want to draw a straight line and effectively stops you from moving off your line, but it appears that you can draw glancing angles very easily which leads away from this theory. The problem seems to come from 'rapid' change of direction - as if there was play in the axis rollers. Well that's what I think, Gary -- --------------------------------------------------------------------------- Gary C. Bartlett NET: garyb@abekrd.co.uk Abekas Video Systems Ltd.
