I am acually running Mac OSX 10.8.2 on a 2.5GHz Intel Core i5 @ 4 Go (1600 MHz) DDR3.
I am using Apple Message apps for synchronizing my SMS with my computer. The problem is that everytime my computer come back from a sleep, I have a memory leak in Message and I need to quit the process in the Activity Monitor because It's freeze my computer.
As you see, on the screenshot, Message use 1.45 GB and will continue to grow up if I don't quit the process.
I haven't found anything about this memory leak, and I would like to know If someone know how to fix the problem. When I Quit Message, I can reopen it and it works without any problem.
