I used to have an IBM laptop which ran Blender 2.6 perfectly fine. I have recently bought a new one with an nVIDIA 8800gts card that had its drivers updated when i bought it. When I ran 2.7, it was slow and unresponsive at times. I would click the mouse and drag, but no selection box came up. This doesn’t happen all the time though, it’s like a 50/50 chance. Also, when I hit ‘B’ again, the select circle/cursor remains wherever i move it (so if you moved it across the screen, you could essential make a line with it like in MS Paint). I reverted back to 2.45 and 2.46 but they did the same thing. Could someone help me out? this is becoming very frustrating :spin:, thanks.
Also, i have a cpu monitor on my desktop, and whenever i minimize Blender, i can see that the usage spikes whenever i use it. I have a 1.86ghz processor or something, but that should work fine right?
