> 1. Run Task Manager
> 2. View->Select Columns
> 3. Check "GDI Objects", press OK
> 4. Run Visual Studio 2k3
> 5. Create new Window Forms application
> 6. Put into the form "ListView" and enter 5 items.
> 7. Run Application
> 8. Force application to refresh (e.g. move another window above this
> application)
>
> You will see that GDI objects increase really fast. The same situation
> with Add/Remove items, GDI objects still increas. I've noticed that I
> can increase it number even till 10k and after that application starts
> to glitch.

> It seems that the problem can be solved after:

> GC.Colelct();

> But this is *really* bad solution which significant impacts to the
