I'm not sure if this will help your exact problem, but I've got into the habit of issuing

clear all
release all

After changing forms/classes and before re-running.

>If I delete a form (as opposed to 'remove'), it appears to leave the compiled version i.e. .FXP and a .BAK file. I must have spent an hour on friday pulling my hair out because a program that I had compiled always seemed to run using an older version and it turned out to be these FXP files that were causing the problem.
