For some odd reason, many apps downloaded from their source (well known websites) are not opening for me in Lion. They just try to open, stays in the Dock, does the blinking dot and they goes back without opening.
I've noticed this with few apps so far. But does not happen to any of the apps from the App Store so far.
I've done Disk Repair, Permission Repair etc. without success.
What might be the problem?
EDITS:
"The Hit List" was one app with the issue. It's universal, 64Bit. However, I went and deleted everything related to it and it's opening now. So, I guess the problem was with corrupted preference or support files.
Thanks everyone for their answers.
