David,
I don't have a tool in the environment but all my objects, forms, text boxes etc come from the 4 classes that i have.
In responce to Hilmar's suggestion, I also have not added a project hook, at least not on purpose, when i look at the project properties there is not project class listed either. I would like to get to the bottom of the problem rather than have code that clears all etc at the start as i don't have this problem with other projects that use the same classes.

>>I have a very wierd problem. In one of my projects after i compile it, if i try to compile it again i get a warning saying "file class1.vcx is in use and cannot be recompiled". if i do a clear all and a close all it wil compile again. this is a real pita and it does not happen to my other projects, has any one any ideas on this?
