yes app alias, (or symlink), even placed in Applications folder does it. Right click "show original" works fine though. I restored in recovery and it went away, but then it offers beta 2 again and not beta 3 yet. I'll try to avoid beta 3 now till bata 4 shows up. It's a bad bug if you use alias or symlink for apps.
Edit: Beta 2 after restore turned out to actually install beta 3 and the problem abover returned.. ugh. Back to restore again.. geeze.. tedius...
