Problem spotted.

That framework is quite simply hokey. It produces an unreliable debugging environment (when just sitting at the Visual FoxPro debugger), causes single-stepped code to take alternate paths than run-to-cursor code, and it hooks into things in such odd ways that code I've used for over a decade does not work when Mere Mortals "hooks" into the environment.

It's forced me to write some notable workarounds.
