Launchbar Commander is a really useful tool!
However, I too have noticed that the utility when running steals focus when the context menu/right click functionality is being used. For example, when LBC is running and I try to highlight a number of emails in Outlook and move them to another folder with the right click/Context menu - the menu just blinks off and I have to start over and try again. This also happens with other applications as well. This is not a show stopper for me though, the usefulness of the application trumps the annoyance.
Mouser - Thanks for taking the time to create this utility!
