I cleared my IE cache, I shut down the firewall, I updated to IE7. The result is the same.

Hope this may help you to solve my problem.

I would very much like to try out Plan-G but I have difficulties in installing this program. After I unzipped the download file and click the yellow plane icon, I receieved this message:

"Plan-G is unable to launch the Google Maps interface. Please check:
1. you have IE6
2. javascript, ActiveX and Binary behaviours are enabled
3. clean the browser's cache
4. check for security settings or browser plug-ins"

I have .net framework 3.5 sp1 & IE6.0 installed. But what exactly I have to look for and do with points 2, 3 & 4, I am totally at a loss. Your help would be much appreciated.

Stephen
