After installing OS X ML, Photoshop CS4 crashes constantly, any clue how to fix this or why it is happening?

I downloaded and installed OS X Mountain Lion last night and everything was working normally. I started working in Photoshop CS4 this morning (the first time after installing ML) and when I try to drag a layer to create a new layer, or when I try to move a layer to another PS document, it shows the beach ball of death and then crashes. It has crashed on other occasions, not just doing these actions. Before installing ML I haven't really ever had a problem with PS crashing. I reinstalled PS earlier today to see if that would help but it still crashes. Any ideas on why this is happening or how I can fix it?


Thanks for any replies, in advance.

While CS4 is getting a bit old in the tooth now, Adobe says there are no known issues as of the 25th !


Adobe CS apps & Mountain Lion: No known issues

BUT that comment thread there is a bit long ->


If you encounter any issues, please report them on our bug reporting form.


OR:

Well if anyone was still looking at this looking for answers I have figured out this so far:


If I go to the system preferences panel>energy saver> and unchecked "Automatic graphics switching", I can now move layers without photoshop crashing.


or


If I use the keyboard shortcuts for moving layers instead of moving them with my mouse I can move layers without photoshop crashing.

Just searching around the internet actually. It wasn't easy to find it, and I wasn't sure it would work but it did. Also, not sure if I put this in my post for an "answer to the problem", (and yes I am too lazy to look). I unticked that box and opened photoshop and worked and the next time I went to open photoshop I ticked the box again to see if it would continue to crash and it didn't so I think it might just be a one time thing and then your good to go.
