Re: How do you deal with dead EvenHandlers?

Hi Thomas, I hope you don't mind me following up again on this topic but after implementing onUnload to remove event handlers (which worked, of course) I realized that this approach is inappropriate for my application. The reason is that my application is basically modeless - meaning that I can

Re: How do you deal with dead EvenHandlers?

Re: How do you deal with dead EvenHandlers?
