User Account Control warning

Startign today, every time I open dragon, the WIN7 user account control warning pops up asking if I will allow Dragon to make changes. I think this began when I inadvertantly switched IE* to the default broswer and back again. I have uninstalled Dragon, run repair, but the issue remains. Any ideas?

Maybe Comodo Dragon want to upgrade to the newest version?

I am running the latest version.

I gave up. I ran CTM and eliminated the problem.
