Exception when removing the last kernel in a MS task:

I can't reproduce it.
Can you give a bit more details ?

[pascal-ballet]

1. Go to the kernel1, and add the following code (I think this code it do NOT matter, but I repeat exactly what I done):
   Matrix1[p]++;

2. Go to the Scheduler tab, select the default task and add again the Kernel1

3. I ran the application for 2 seconds then stopped it.

4. I add again the kernel 1 in the task.

5. I remove one of the kernel (I do not remember which) but then the exception occured each time I remove the last kernel in the list.

[jeancharles-roger]

I still can't reproduce the exception. I'll try harder ...

This event is called twice. The above screencapture is for the 2nd call after deleting the kernel in the task. The second item (index 1) is empty.

Thank you for the analysis. I'll try to prevent this
