Middle Mouse Button Zooms Intead Of Rotating

You know how the middle mouse button is supposed to rotate the view? Well sometimes I start up Blender and it zooms instead of rotating.

Any idea why it’s doing this?

Ctrl-Key is stuck.

I thought of that, but it happens with different keyboards.

It seems to be a quirk, I get it too. Just bang the Ctrl and Shift keys a couple of times – clears the buffer or whatever.

I’ll try that. It sure would beat restarting Blender over and over.
