Greetings!

I still get the exception if I don't use the ".Document" reference. My
code is suppose to wait for IE to return a "not busy" result before
going on.

I recall Mr. Hammond giving an example where he was waiting for IE's
"ReadyState" to return what would be true when ready state was
obtained. I used to use a method to determine ready state and then go
on to determine if IE was "Busy". I found that using the "Navigate2"
method seemed to obviate the need for checking IE's ready state.
Perhaps I should leave the ready state method in?

Here are a few snippets:

################## start of snips #####################

In main I call:

            o_AleApp.NavigateIE(s_URL)
            ##fire events after nav test
            o_AleApp.ClickCrossFrameElement(1, 'Sub1t')

In NavigateIE I run:

    def NavigateIE(self, s_URL):
        i_Sleep = self.GetDelaySecondsBetweenPageNavs()
        print "Class: AleAppWebReporter Method: NavigateIE: Sleeping",
i_Sleep, "seconds prior to navigating..."
        time.sleep(i_Sleep)
        print "Class: AleAppWebReporter Method: NavigateIE: Navigating
to:\n" + s_URL
        self.o_IE.Navigate2(s_URL)
        ##now lets make sure the page has fully loaded                
        s_NotBusy = self.WaitForNotBusy()
        if s_NotBusy == 'TRUE':
            return 'TRUE'
        else:
            return s_NotBusy

In WaitForNotBusy I run:

    def WaitForNotBusy(self):
        print "Class: AleAppWebReporter Method: WaitForNotBusy:
Current URL:", self.GetIELocationURL()
        i_IEBusy = int(self.GetIEBusy())
        print "Class: AleAppWebReporter Method: WaitForNotBusy:
i_IEBusy:", i_IEBusy
        if i_IEBusy != 1:
            return 'TRUE'
        else:
            i = 1
            i_State = 0
            while i_State == 0:
                print "Class: AleAppWebReporter Method:
WaitForNotBusy: Waited:", i, "seconds for IE to complete
downloading..."
                time.sleep(1)
                i_IEBusy = int(self.GetIEBusy())
                print "Class: AleAppWebReporter Method:
WaitForNotBusy: i_IEBusy:", i_IEBusy
                if i_IEBusy != 1:
                    i_State = 1 
                i += 1
            return 'TRUE'

In GetIEBusy I run:

    def GetIEBusy(self):
        return self.o_IE.Busy
