After reinstalling Poser the application crashed really bad. After the next install and trying to use the Crop Tool I get the message:

:Can't complete the request because all Scratch disks are full".

I have GB of free disk space on my C drive.

I don't know how to make it work again. In Preferences the Scratchdis is set to C: but it seems PS ignores it. Something got corrupted and I can't find it. Can somebody please help?

Operating system is XP.

I just solved the problem. It was something very strange that I had to do two years ago to make the crop tool work. I forgot all about it since it has to be added manually in the Height and Width boxes and is not documented anywhere.

I had it set to 850 x 1000 at 300 Resolution. Pixelinches was selected.

PS tried to crop at 850 x 1000 inches and not pixels. This ate up all of 40 GB and it asked for more. pix had to be added manually in the Width and Height boxes to get a reasonable file size. The question I am asking myself is: why am I not able to select pixels in the first place?

Because you must have your Units & Rulers set to inches. If it's set to inches and you want to input pixel dimensions in the width/height you have to add pix to the numbers to override the inches default.

 

Edit > Preferences > Units & Rulers

 

Units and Rulers were set to inches. What I didn't remember was to add pix manually to the numbers.

I really thank you for taking the time to respond and you are the only one (so it seems) who knows about this.

Yesterday I used Google to find answers to Scratch Disk Full. I found every possible reason except the one you just offered.

Thank you again for responding.

You're welcome.

The reverse is also true. If you have the Units & Rulers preference set to pixels and you wanted to crop inches you would have to add "in" to the numbers in the width/height values. Any time you want to override the default you have to add the unit to the numbers.
