InfoPath Memory Issue - Internet Explorer

[Don Hurley]

Hi,

I have an InfoPath form that I am hosting in Sharepoint using the
XmlFormView Webpart. I am doing post backs to have dynamic loading of
controls (ie. DropDown list changes, load another dropdown). Every time I
post back, I see Internet explorer take more memory. It does not give it
back until after leaving the page. I am not sure where the memory is going,
whether it is an infopath/xmlformview/form services issue. How can I get the
memory back without leaving the page.

Thanks,
Don
