What's the answer then, other than disabling the feature? As Default Folder is fully integral with my whole day to day workflow of using everything. Not just PM. I will be upgrading to Snow Leopard sometime soon.
When editing football I have each folder for each client open around the desktop. I save images to each client as I'm editing in PM, simply hovering over the relevant folder underneath PM and Photoshop. To work any other way would slow down the whole process. That to me is crazy. Why change it now?
