I'm getting the following error when trying to find an app on my hard drive. I use the Alfred interface, push the command key down and click on the app. This should reveal the app in the Finder. Instead, I get a dialog, hidden behind Alfred, so it makes it look like Alfred is hung, because I can't see it and cannot interact with the front window of Alfred.
I'd upload a screen shot but your forum won't let me. So here is a movie on youtube: https://youtu.be/4Hkjp-Eop4s which shows the problem in all its glory. The dialog behind Alfred forces Alfred to hang. If I didn't have multiple desktops I'd be screwed here.
