Hi Alex,

I have had bad luck with this type of loop waiting for the WebBrowser control:
>>>	DO WHILE toBrowser.ReadyState # lnReadyState AND lnX < lnMilliSeconds
>>>		DOEVENTS
>>>		lnX = lnX + 1
>>>		Sleep(1)
>>>	ENDDO
Even the DOEVENTS / Sleep combination do not seem to be enough to allow the control to do it's job. But stepping through the code does. That's what makes this fustrating to debug.

I would try one of these 3 things:

1) Change your DOEVENTS to DOVENTS FORCE
2) Make sure _VFP.AutoYield is set to .T.
3) Don't use a loop to wait for the browser to finish, instead hook into the NavigateComplete2 event. This is similar to a CallBack and is the preffered methodology for dealing with Asynchronous processes.

I hope this helps,
