>>Keep in mind that this does not always work in VFP6. In VFP3 and VFP5 if you add a method with the same name as an existing method (in another control type) it will behave identically. In other words, 'RELEASE' will release your toolbar. However, this is NOT always true in VFP6.

I think Barbara may be slightly mistaken as to the suggested technique here. In my base classes, if any VFP class is missing a .Release() method, I add one to my base class with just one line of code:
RELEASE This
In other words, I do not assume that VFP will behave the same way just because I named it the same. This code, on the other hand, will work in all cases that I have found, including VFP 6.

Thanks, incidentally, to Doug Hennig for illustrating that technique to me.
