Put a SET STEP ON above your first WAIT WINDOW and see the values there manually.

I know it's not a popular thing to do, but you could put a timer on your form firing once ever 20ms or so, to examine the values there and if they have changed, or if they are not what you're expecting, issue a this.Enabled = .f. and then SET STEP ON for you to examine in your code. You'll get a hint as to what was happening when it was changed. Then you can break at some prior point and use a breakpoint that is "break when expression has changed" to locate when it changes. Make sure you use the fully qualified variable name as the code's instruction pointer will move in and out of "this" and "thisForm" objects as events fire. Something like:

IIF(_screens.forms(1).Name = "yourFormName", _screen.forms(1).myObject.myOtherObject.myVariable = whatYouExpectItToBe, .t.)

Then you can find on either the immediate code or call stack what caused it to change.
