It appears I may be wrong base on a number of tests that I performed
because of both of your help
First you program did produce the same results that you got
I then physically pasted 500 rectangles into a form and again minimal
memory changes. (although while I was pasting the memory did drop but
it came back)
Finally I took the form that had the problem stripped out all the code
and put it in a new project and guess what - minimal memory changes
So it appear that I have a "memory leak" somewhere within the program.
I guess the next step it to create break points to try an isolate the
memory leak unless any of you have an idea?
BTW Thanks for all your help because I was obviously barking up the
wrong tree
