In Visual Basic 5, the control loads on the form properly. However when the ".Navigate" event is called, VB returns run-time error 5: "Invalid Procedure or Call Argument". This happens in the sample VBrowse program, even though the IE control works fine. In a related vein, if you dump the Mozilla Control into the "Browser" form that comes with VB5, and replace the IE control with the Mozilla control, the control doesn't seem to respond to the ".Navigate" command at all, nothing happens.

It does work, but not as advertised! You need to include the "optional" arguments, eg: MozillaBrowser1.Navigate2 "http://www.mozilla.org/", 0, "_main", "", "" works fine.

The problem is caused by an invalid test on the second argument. If this argument is omitted, the Navigate returns E_INVALIDARG that VB reports as an error. The workaround is to add 0 as the second arg.

This bug is mouldy. The situation now is that the control has a hack around problems in NS_InitXPCOM that make it work in VB. Additionally the problems with optional arguments with Navigate have been fixed for quite some time.
