Wilbur Locks After Erosion Cycle

[arakish]

I am working on a 4000 x 3000 pixel greyscale surface bitmap (PNG) use the Filter > Erosion > Erosion Cycle. After the Erosion Cycle has finished (progress bar box reaches 100% and closes), I try to close the Erosion Cycle dialogue box, then Wilbur locks and crashes.

I know Wilbur is uber slow, but is this a true lock and crash, or is Wilbur still doing something and just not showing a second progress bar to indicate this?
