I've had two identical crashes of 111c in the past 30 minutes.
1) Double-click on an item to edit it
2) Error message pops up that begins with "Run-time Error..." but then disappears too quickly for me to read more.
3) At the same time, tabs begin rapidly closing, then the program disappears.
4) When I start back, some of my tabs are gone and several have lost their color
5) Returning to edit the same item as before does not cause a repeat of the problem.
Don't know if the abbreviated error message is enough for a clue as to what might be happening.
I see d is out so I'll upgrade to that.
