Open question about LR CC. It has been running on my Windows 7 Home Premium, 64 bit, with AMD Phenom11 4 core processor and 16gb ram but really stresses the CPU at times. This evening while in the Library Module, it has frozen and I can only get out of the program by closing LR CC using Task Manager. The CPU runs at full throttle throughout and until about a minute after closing LR. This has happened several times in succession. Has anybody else had this problem and is there a fix I can apply?
