Short description of error
This is similar to my bug report on edge loop selection in 3d edit mode. If you go into UV editing, you can't edge loop select. Basically, if you have both left click select and 3 button emulation on, there's basic interface actions that don't work. Which has been true for me since I started using Blender (2.4x days). As long as right click select was the offical mode, I didn't think of it as a bug and never reported it. But now that left click select is official, and so very many people don't have any middle mouse button (I do, but I find it hurts my wrist to use it for more than a few minutes), I figure I should say something. As much as this is a particular issue, I hope that you guys just do your general UI test tasks with the combination of left click select and 3 button emulation mode on.
Exact steps for others to reproduce the error
- Make a mesh
- UV map it
- Go into the UV map editor
- Set your preferences to 3 button emulation mode and left click select.
- Try to select (or deselect) an edge loop. Alt + click and Shift + Alt + click don't work.
