Saying this is a SERIOUS problem is an undertsatement.
I went to simply burn an iso file,m and had the same as others here.. nothing happens when icons click.
After reading the forum, like others here, it appears it has to do with Norton Windoctor the registry cleaner that comes with Norton System Works 2007.
I reinstalled 10 and had no problem, ran Norton Windoctor and couldn't start anything up.
I then went back and UNDID the registry fixes.. and STILL couldnt get EMC 10 to work... had to uninstall and reinstall everything over AGAIN!
This has NEVER been a problem in the past, and ids a big one now.
Someone needs to look into this from Roxio.. this should not happen.
