Photoshop is Out of Memory... But I've got 32GB!

[SnapperUK]

Have just started having a problem with Photoshop CS3 claiming to be out of memory. The exact message reads. "Could not complete your request because there is not enough memory (RAM)."
I am getting this when I trying to convert a scan colour negative (100 mb) to B/W using the Black & White Adjustment.
What is even more confusing is that this machine is maxed out with a huge 32GB of RAM. It is a 2 x 3.2 ghz Quad Intel Xeon running 10.5.6, so really should be able to handle this without a sweat.
In PS performance has allocated a full 2810 Mb and has two scratch disks each with over 250 GB available.
So far I haven't had this problem with other operations and have handled way bigger files.
Any thoughts?
Thanks

Have you run through Adobe's troubleshooting script?

2814 mb... that's just a little shy of 3GB of memory u've given PS to work with... u have 32GB... with only 3 GB useable.... ur machine will most definitely choke on a 100mb RAW.

PS is still 32 bit on OS X - 3GB is all it can directly use.

Don't see any reason why that won't work. Update the app?

Did you allocate MB or Mb? Huge difference.

It's a 100MB scan, not 100MB RAW.

Sorted...

I followed the Adobe troubleshooting and first thing I did sorted it.
Basically it was a problem in the preferences. I trashed them and restarted and it is working.
Thanks
