CS5 crashing on file double clicks

Since doing a clean install of Lion on a new SSD I find the any CS5 app crashes 90% of the time if I either double click on an icon or right click and open in...

I also find they regularly crash when quitting too. Is this common or is there a fix? I could wipe the disk and install again but that is going to take a lot of time.

I'm using an Early 2008 model Macbook Pro 2.6ghz with 4gb ram. I also have Suitcase Fusion 3 installed.

 

If anyone is interested, worked this out. A common problem to do with permissions. I had to add to add permissions for certain preference files. All seems stable now.
