I’m running Blender using a Sapphire HD 3850 AGP 8x graphics card under Win XP 32. I have 1 GB RAM, a Microsoft natural keyboard, a Kensington Expert Mouse (4-button trackball) and a 3Dconnexion Space Navigator PE. I’m working through Blender for Dummies (which tells you that I’m still wet behind the ears).
I’ve noticed some odd behaviour, which might be a bug, system issue, or maybe I’ve hit an odd key that’s gumming up the works. For example, I’ve been trying to set the 3D cursor with left-button click. For a while I’ll see it, then suddenly when I click it’s gone. I tried tabbing from Object to Edit mode, and nothing happened. I popped up the menu which currently showed “Object Mode”, and it shows “Mode: Object Mode”. Edit mode isn’t even an option on the menu anymore! I’ve also found at times that the “+” and “-” keys stop working for zooming.
Am I doing something wrong, or is this some sort of bug/incompatibility thing?
