all of a sudden Eagle 6.3 (free version) does not respond to mouse clicks properly. Sometimes I can click on an icon like the eyeball and I click on the pcb trace and it works - but most of the time it seems to be clicking the eyeball icon over and over no matter where I click on the pcb. Mouse wheel seems to work as expected but sometimes when I wheel click to pan the drawing jumps to some other location before beginning the pan operation. similar problems in schematic editor. I uninstalled and reinstalled and that did not help. In AutoCAD the mouse buttons work as expected as does mouse wheel for zoom and pan. Other applications seem to work properly.
Mouse - MS Wireless Mobile Mouse 3500
OS = XP Pro
Dell Precision M4400 with 4 GB memory
Any ideas on what the problem might be?
