I referred more to this:
GDI stands for Graphics Device Interface and is in charge of the visible components of Windows. It stores fonts, brushes, bitmaps, and other graphics stuff, as well as lends support to other graphic output devices such as printers.
Everyone owning Windows 9x could do the following to test
-SAVE YOUR STUFF!!!
-Now open as many windows as you can (or run some graphically-intensive programs)
-It doesn't take long before the fonts distort, you can't open more windows, you can't type text in Notepad, it may even freeze.
edit: Don't get me wrong, I don't say that it is the problem, but it could have to do with it. I recommended to run the resource monitor to remove it from the list of possibilities, but he hasn't done yet. Well, another possibility is a limitation in a DLL HFS makes use of...
