.Net control memory not freed in mshtml

microsoft.public.dotnet.framework

I have a large .net control that I am running in MSHTML. The control
simply loads up a number of images, however this problem has been
replicated with a number of other .net controls. When the control is
unloaded by calling up another page none of the memory is freed. Using
perfmon I have a flat line for both virtual and private bytes that is
never freed until the application is shut down.

For my own controls I can workaround this problem by calling
GC.Collect() in the dispose method, however my problem is with third
party controls that do not do this. It is almost like the GC stops
working when the page is closed.

Has anyone else seen this problem. Is it something I am not doing in my
code or is it normal mshtml behavior. If so is there a workaround to
clear the memory or has the 3rd party application got a memory leak
bug?

Thanks for your help in advance.
