Since upgrading to Yosemite, After Effects 10.5 consistently crashes whenever I use the color picker tool. The crash occurs after clicking the color picker tool, then moving the cursor outside the bounds of the tool button.
This occurs on 2 different Macs (MBP & MP). Both computers were upgraded from Mavericks.
I tried uninstalling After Effects, and reinstalling it, but that didn't solve the problem.
Here is a snip from the crash log that may have a clue as to what the problem is.

After Effects CS5.5 is not supported on Mac OSX v10.0 (Yosemite). See the system requirements for After Effects CS5.5.
See this for details of what versions of After Effects are supported on that operating system:
Try using the system color picker. You can set this in preferences > general.
