canny edge detection unresponsive

[pr4deepr]

Hi
I'm opening this issue here as its an error in assistant and not when I run it otherwise.
When trying canny-edge detection in assistant, if I change any values it becomes unresponsive and stays on red forever..

I can close and go back and rest of functions seem to work ok

If I happen to enter a value which is outside the range , say a negative value; it becomes unresponsive and if I close and run another operation, like a tophat for example, it stays at red, or if I change a value it becomes red:

another operation after above error, where it is unresponsive.

Thanks
