#243 Interface shifts while drag-selecting

[Anonymous]

System: MacBook Air running Mac OS X 10.6 (Snow Leopard) and Wings 3D (either 1.2 or 1.3.0.1).

When I attempt to drag-select in Wings 3D, the contents of the Window (everything but the OS frame) shifts a few pixels and blurs very slightly (probably because sharp lines are no-longer pixel-aligned); attached files illustrate this. In order to select vertices correctly, I have to know/remember where they were before the shift (co-ordinates selected are based on pre-shift locations). I'm guessing it's a problem somewhere between Wings 3D and OpenGL.

The behaviour wasn't always like this, even with this version of Wings 3D, so I'm unsure what has happened. Maybe it's an OS or OpenGL issue, but it's frustrating. I tried deleting the Wings 3D Preferences file (the only config file I could find), and it made no difference.

Any help would be welcomed greatly. Other than this issue, Wings 3D is great free software, and a pleasure to use.
