C++ Dialog Editor Bugs?

[Silver Ghost]

When I create a new Dialog in Visual C++ 6.0 the dialog editor window creates a small black box in the top left hand corner of the Dialog Editor window. It has basically created a dialog box with no size and the Cancel/OK buttons off the screen. I can resize this by dragging but often the buttons do not reappear and I hace to manually edit the .rc file to move/delete them. When I open Dialogs for editing they are also shrunk to vertically. Both these "bugs" cause the Guides to get messed up, I can usually drag the Left/Right/Top guides to get them back, but haven't found a way to get the Bottom one back, though this doesn't concern me too much. Has anyones also had this problem? I wndered if it is caused by my display setup. I am using a Dell Precision M50 laptop with nVidia Quadro4 700 GoGL graphics. This is running in Horizontal Span Mode with a CRT giving a desktop of 2560x1024. The nVidia driver is set to not allow Windows to Span multiple monitors. I use the latop as the Primary Display and the CRT as secondary. I am 'using' Visual Studio on the CRT, though the problem also appears if I use the laptop display. Why do I still work here?:(
