Selection Zooming issue

[Paul]

Hello,

I'm experiencing an issue with using the mouse selection zooming (where you select a rectangle to zoom in on).  After a few successful zooms, an error is thrown (ArgumentException: Width and Height must be non-negative.) when trying to zoom in to fine detail.  I assume this has something to do with rendering the pan/zoom bar, but I'm not certain.

I can catch the previewMouseUp event, but I'm not sure how to correctly check/handle this issue.

Any help/guidance would be appreciated.

Also, the interesting bit of the stacktrace from the exception:

After looking at an example project posted here by an admin (which did not have the problem I was seeing), I eventually realized that the example project was using newer DLLs than I was.  After downloading the update, my issue has been fixed.

Thanks,
