Hi,
As said, Google maps does not work well with Mapsuite.
To Reproduce:
1. Go to the websamples provided by Mapsuite (Included with the latest beta).
2. Do not load google map in master pages so go straight to the aspx page.
eg. localhost:1347/Samples/Layers/UseGoogleYahooWms.aspx
3. Select Yahoo map and Focus on a location.
4. Switch to Google maps. Notice how it jumps to a new location ?
5. try scrolling/zomming in google maps, It does not work but it works if you switch back to yahoo map.
Regards.
