Just a heads-up for everyone.
If you find yourself crashing after using the new slot library feature, the issue appears to have been fixed with either SP2.0 or 3.0.
Here's the issue: if you drop in the new slot feature and select the edges of the part to locate it, and then you edit the sketch to change dimensions, you will crash coming out. If you haven't tied to the edges, or you change dimensions by double-clicking rather than editing the sketch, it will work ok. Here it crashes on SP1.1, but not on 3.0.
