No problems on two Macs with 10.10.3. It also fixes multiple monitor issues in 10.10.2.
"It also fixes multiple monitor issues in 10.10.2."
If you you want to edit ExtendScript scripts and using the ExtendScript Toolkit (ESTK) on OSX 10.10.x, the ESTK will be incredibly slow and jumpy, if you are typing in code.
The ESTK could be a massive pain point on OSX 10.10.x. Not so on Mavericks OSX 10.9 or below.
