You're not dumb, you just don't have that knowledge. If you know how to go into the code window (a way to do it is just to go into design mode for a form and then click VIEW > CODE) and then scan through all of the code there to find something that might be there. But, I'm assuming that you might not know how to navigate through the code, nor look for what is the problem. So, maybe someone else has seen that before and can offer some hints.
