How to tell when IDE is done loading

Mike,
Your plugin suggestion was a good one. When I removed them all I am
now getting the expected behavior.
I now need to add them back in one at a time to find the one that is not
setting allowinterrupts to true.
It does seem that allowinterupts is the correct vehicle to tell when the
livecode part of the IDE has been fully initialized, but because of user
written plugins it is not totally reliable. Any other thoughts? I am
going to submit an enhancement request and see if something more
reliable could be made available longer term.
Regards,
Mike
