What OS do you have? Does it still work in CC 2014 on that system?
There have been a number of folks on Yosemite with issues doing this (and not just with Adobe software either - something is different about how Yosemite draws windows in its interface).
Not sure about 2014 still working. But Photoshop and Premiere work fine in the new versions. I'm on Windows 7. Not noticing any other programs with issues.
