Using Smart Select 1.2.0 and Blender 2.78a on OSX 10.10.5, I couldn’t reproduce his crash(nor even finish recreating it, it doesn’t let you hit undo during bevel). I did get some other crashes when I first started but now they’ve gone away and I can’t get them to happen(of course it’s when I’m running out of a terminal and could get a possible error message). I’ll keep messing with it for a bit.
One thing I’ve noticed that seems wrong is that Smart Select doesn’t realize when a regular selection event has taken place and the operator should go away. This maybe a contributor to existing or future trouble. For example, if you select the loop of edges on the top of a cube, then just normal right click an unselected edge, then change the mode with alt-scrollwheel, the selection reverts to the original loop with the new mode. This behaviour might be related to the next thing as well.
Also, I may have found a different bug that happens on Windows and OSX though:
- Create a cube
- Hit Tab to enter edit mode, change to Edge Select mode if necessary
- Alt-RMB to select a single edge
- Alt-scrollwheel(or ctrl-scrollwheel) over a different edge to change mode/angle, you lose your selection and the edge you’re hovering over is selected.
This doesn’t seem like intended behaviour if alt-scrollwheel is just supposed to be a mode select.
