Crash dump when trying to rotate object

[w3dut]

I have an object that I'm trying to rotate in "X" 90 degrees. I've done this thousands of times but this particular object will not allow me to rotate it. I can select the object faces, then select .Rotate, then select "X". Then when I press the TAB key, Wings3d generates the crash dump and when it returns from that, the mouse cursor is INVISIBLE.


BTW, I've attached the crash dump but the file that caused it is 406kb zipped and I can't attach it (is there another way to upload the file if needed?)

Any ideas, help would be greatly appreciated.


Thx.

Jeff
