Brilliant example that this is, be warned!
With Excel 2000 under Windows 98 (I havent tested it with any other OS combos but I would have thought it was the same) this sample turns the toolbars and menus off permanently. e.g. if you go to open excel after running this example you get a spreadsheet and thats it, no amount of right clicking etc will let you turn the toolbars back on.
How to get round it...
Open up a VB project and copy the code from the MDI_Formload into the form_load of a new VB form. Alter the code so the excel toolbars are set to true and the border and caption bits of the window long are set. Run the form et voila! Sanity restored and excel back to normal.
Quite why M$ saves the windowstate like this is beyond a simple soul like me, but theres probably a method in their madbess...
