I have been experiencing a very annoying problem that I have not found a solution to yet. Every once in a while when I start debugging a project from the Flash Builder (4.0 now, 4.6 before), all of add-ons for Internet Explorer become disabled and there is no possibility of enabling them. This includes Flash so my project does not start.

Sometimes restoring default security settings in IE helps, sometimes it doesn't. If it doesn't, I restart my computer which... sometimes helps, sometimes doesn't.

If it doesn't I am forced to reinstall Flash and after that all of the add-ons (including Flahs) are enabled again... until next time.

I have been looking for solutions on the Internet, but haven't found anything related to the topic.

I am running Windows 7 (x64), Internet Explorer 8 (tried both 9 and 10, but the problem was the same), and McAfee OAS.
