Photoshop preference panel failed to open.
If i try to enter preference panel, by any way, then will give me a message box
"An integer between 96 and 8 is required. Closest value inserted."

And it will show me General panel instead, and if I try to enter performance panel, will get the same error.
I've got 16GB memory installed, and I got 8.7GB of free memory available. Only 2MB is IMPOSSIBLE.

So will adobe fix the logic of how to fetch available memory? I think problem will be fixed by that way.
I googled for the solution and someone told me this problem happens after updating to FCU, I don't know if it's right.
