A few days later... I forget the point here < g > but I tried to test this anyway. I run the form in VFP6 on a Win95 box w/Netscape 4.7 as the default browser and all the latest service pack stuff for VFP and IE4. The browser control on the running form is definitely IE - right click shortcut menu lists "favorites" instead of "book marks". But the form runs fine and navigates separate from any concurrently open browser windows (netscape & IE).

uhhhh... what else was I suppose check?
