.NET forms doesn't get disposed

[justfortunate]

I wrote a simple form with a button, on click of a button it opens up another windows with few more buttons, listboxes etc. I noticed that when I click on the button the memory utilization goes up and when I close the window the memory doesn't get released. I also called the dispose method and also the GC.Collect() but still I don't see the memory getting freed but instead the utilization increases everytime I open the window. This is a major problem I am facing with one of my application at the client's place and the memory utilization goes so high that the application feezes after reaching a limit. I am using Dispose method in all the objects. I am ensuring all connections are closed and GC is called. What could be the problem? Appreciate any help/tips.

What are you doing in there that causes so much memory to be eaten? I use this stuff on microcomputers and don't come near running out of memory.

Hi,
The test code I wrote was very simple

On btnTest_Click event

frmMyTestForm frmMTF = new frmMyTestForm();
frmMTF.ShowDialog();
frmMTF.Dispose();
frmMTF = null;

On the frmMyTestForm I have a Close button which calls this.Close()

frmMyTestForm has about 25 UI objects (buttons, listbox, etc) without any code attached for testing.

In my commercial application I have datagrids on the form and some UI objects. I am making sure all the data is cleared, the objects disposed and connections clcosed. But just the instantiation of the from object uses up lot of memory which is not getting freed. I tried to use Memory profiler and ensure the count of my form is 0 after closing by removing any static or circular references in the form etc. but still unable to clear the memory utilized.
