Worked: Haven't tested.
Short description of error
While in Cycles, I used the "Project from view" UV unwrap option. After resizing the UV image, the layout got squished. I tried project fomr view again to fix it, but it stayed warped until I switched to the internal renderer and used the option, it went back to normal.
Exact steps for others to reproduce the error
To reproduce: While in cycles, use project from view on an object, then resize the default UV image horizontally or vertically. The wires should get squished. Try projecting it again in, still in cycles. It won't fix the squishing, but if you re-project it in BI it will fix the problem.
