The problem has been there about nearly 8 months. It was running smoothly when I'm using cc 2014.0, but since the app upgrade to 2014.1, the ui changes (maybe to adapt higher DPI (read on update log)), program started running slowly. The program starts to hang or stuck about 10-20 seconds whenever I try to click on something or try to open a new window or create a new file. I cannot do anything normal on it. I have to use back to 2014.0. Since Creative Cloud has the version cc 2015, I thought this problem could be fixed, but it's not. Please fix this problem as soon as possible!!
Please don't ask any error log or computer info!
No error logs because it doesn't quit or appear any wrong information.
This happens on any mac, including OS X 10.10 and 10.9, Retina screen and non-retina ones, old and new ones......
No flip4mac or anything could effect the program.
