Just to clarify: My original bug report did NOT
involve any mouse interaction. (Although I
have also observed the behavior that Ethan
describes when dragging with middle mouse
button pressed).
By the way, here is another (similar? related?)
problem:
set xyplane at -10
splot exp(-x**2-y**2)
Crashes (but WITHOUT any assertions being
fired).
For comparison:
set xyplane at -0.1
splot exp(-x**2-y**2)
is fine.
Best,
Ph.
