[Qgis-user] Problem Displaying Google Satellite Layer in QGIS 1.7.4 Using OpenLayer Plugin 0.93 on Windows 7

When I try and add a google satellite layer to my project, I get a python error and traceback  as follows:
            An error has occured while executing Python code:

            Traceback (most recent call last):
              File "C:/Users/bbruce/.qgis/python/plugins\openlayers\openlayers_layer.py", line 109, in draw
                self.render(rendererContext)
              File "C:/Users/bbruce/.qgis/python/plugins\openlayers\openlayers_layer.py", line 164, in render
                olWidth = rendererContext.extent().width() / olRes
            UnboundLocalError: local variable 'olRes' referenced before assignment
    
            Python version:
            2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)]


            QGIS version:
            1.7.4-Wroclaw Wroclaw, 411aff6
After I close this window, a QGIS error window appears with the message: "Could not draw Google Satellite because:" with no other text in it.

I have one vector layer displayed, this has a CRS of 26914 (NAD83 UTM Zone 14), my project has a CRS of 3857 (from reading list postings this seemed to be the appropriate CRS to use) and I have "On the fly reprojection" enabled. \

I can see my vector layer OK but not the google satellite layer. I have verified that QGIS is communicating with the WWW by connecting to an external WMS server.

Can someone help me to get google satellite imagery working, please.
