Google Satellite and Google Terrain basemaps cannot be partially transparent in Internet Explorer

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open MORIS in Internet Explorer 8 or earlier. Have the basemap set to Google 
Satellite or Google Terrain.
2. Decrease the opacity of the Google basemap using the opacity slider in the 
"Basemap" menu. If the opacity of the basemap is less than 100%, then the 
basemap is completely transparent. The basemap cannot be partially transparent 
in IE8 or earlier.

What is the expected output? What do you see instead?
The expected output is that the user could adjust the opacity of the Google 
basemaps to be partially transparent. Instead, the Google basemaps can only be 
completely transparent or completely opaque in IE.

Please use labels and text to provide additional information.
Tested MORIS v. 0.35 on Windows 7 and Internet Explorer 8
Tested MORIS v. 0.35 on Windows XP and Internet Explorer 6

Current workaround: The Google basemaps can be partially transparent in Firefox 
or IE9 Release Candidate.

I thought this might be fixed in a recent release of OpenLayers, but it is 
purely an IE < 9 issue.  I think we should leave as-is or provide some sort of 
alert when a user attempts to change the opacity if their IE version is suspect.
