CS4 crashes when moving layers

Question

I am running OS 10.5.8 on a 2.66 Quad-Core Xeon Mac Pro with 8G of ram.  OFTEN when I simply try and drag a layer above or below another layer, Photoshop will crash.  Has anyone experienced this before and have they found a working solution?

Answer 1

I had this problem in Photoshop CS4 when running Leopard, somehow finally got it to stop when I reinstalled Photoshop CS4 and applied the update, now it has migrated to Snow Leopard (a clean OSX install, to boot) much to my displeasure.
It happens whenever I'm not paying attention... I'll "move" a layer up or down a few slots like usual, or attempt to move a layer when Photoshop might be consuming a lot of resources (i.e. finishing off a filter effect), or even if I try and move a layer while the layer is being transformed and has not been finalized.
The times this has happened are numerous and annoying, always seemingly random. I could have only five active layers and it will happen, or 10 tabbed projects all with 20 layers, it doesn't matter.
Never tried using keyboard shortcuts for layer arrangement—will have to try that now. Will also start sending the error reports.
I should note that this problem never occured in Photoshop CS3. There is one good thing that has come of this: I've been relying on, and thus mastering, Illustrator a whole lot more which is rock solid for me. I love it.
EDIT: I've got a 2.4ghz MacBook Pro (the late 2008 unibody model) with 4GB of RAM. I usually run on the 9400M integrated graphics chip... I can't remember if this happens on the 9600 discrete or not.
