I modified the corrections you made to the "run multiple copies of thunderbird" knowledgebase article to remove the statements about intercepting the command. I've done a lot of low level win32 programming and am used to the standard ways of detecting if another instance is running, and that statement didn't make sense. If I'm incorrect, please explain in general terms how it intercepted it. Tanstaafl 21:32, 6 June 2006 (UTC)
