It may be due to a combination of conditions. I am using a framefork beta that executes command above.

Problem did not occur yesterday, but after some point today error keeps coming up, even after restarting VFP8. I must have made some change, but cannot recall what it may have been.

One thing is clear: The watch window shows a character value for _TASKLIST, and a logical value for NOT EMPTY(_tasklist), yet immediately after that gives error "Variable '_TASKLIST' is not found". Probably it is really a different error and the message is wrong. That happens.

Will investigate more and report. Thanks for your response.
