Photoshop spinning wheel of death

[#1]

Since the past two updates my Photoshop has been giving me the spiinging wheel of death  on most jobs, I work on large files sometimes at 150dpi.

For years it has been fine but since the llast two updates my photoshop is even struggling with a 200cm x 100cm file, I work off a 27inch macbook so I dont think my Mac is the problem.

Anyone else suffer this or have a solution?

Thanks
