Hi,

I'm working with AutoCAD 2011 and have run into the most bizarre problem. My locked viewports sometimes change scale when I use the middle mouse button to scroll in and around my paperspace.

- Yes, the viewports are locked.
- UCSFOLLOW is set to 0 (I'm not sure what this command is but I saw this as the first suggested fix in my preliminary google search).
- It doesn't always happen when I'm working within the viewport. For example, I just recreated the problem by going into the PLOT dialog box, selecting "Window," and then while scrolling in and out over the viewport, in layout space, (before selecting my window to be plotted), the viewport scale changed. I exited my plot dialog box without plotting and double checked the viewport. It's still locked, but the scale is drastically changed.
- This happens in multiple viewports in multiple files, so it seems to be a software/hardware issue, not a file/viewport issue.

Any ideas?
