So, any ideas. Can anyone reproduce this problem? It's a simple cursoradapter, that works every time as long as I don't throw that error in the afterupdate event.

I've tried:
ERROR 'Update Conflict'
ERROR 1585

It won't lock up, though, if I simply save a flag to a property saying that an update conflict occured.

I will use that, but it bugs me that the solution above is the recommended way to handle it and it doesn't work.
