Hi there. I've been working with Revit MEP 2008 (build 20070324_1700) on a Toshiba Satellite laptop, running Win XP, with a Logitech cordless optical mouse. When I use the mouse wheel in 3D views, it zooms in & out (acting normally) but after some time, as use the wheel, it starts to scroll up & down, just as if I pressed Shift while turning the wheel (funny enough, it actually zooms in as it "jumps" up & down!!). I must exit Revit and start again to get the normal zoom procedure - until it does it again... In every other view - plans, elevations, etc - it zooms in & out as expected, it only happens in 3D views. Something with my mouse driver (no problem with AutoCAD, for example), or it has to do with Revit itself? Has someone else had this strange experience? Thanks in advance for any thoughts about this.
