Ok.. I have searched for help with this and I'm not finding a solution so I thought I'd post this. When I run photoshop CS on my macbook I often receive a message when editing a photo that says your startup disk space is full. I have a whopping 70+ gigs available on my harddrive and 2 gb of Ram so I'm not sure what the problem is. I'm only running one harddrive and I don't have much on it. I've tried repairing permissions and it still seems to pop up sometimes. Is there any way to fix this and avoid the error? Thanks for your time.
