help

Hi !
I have some problems.
Can you help me out?

My project is MFC based application.
I am using a DOM object to parse a xml file.
If I open a xml file the memory gets increased by 5 MB.
Per every file opened it increases by 5 mb.
It is not released after opening the file.
If I maximise and minimise the application the memory is released.
What is the solution for this problem.

Regards
G.Rajendran
