Now, tried this (found in the FAQ's for CS)
"faqs"
Make sure you have view hidden and system files turned on in windows explorer (tools> folder options)
Delete the file: New Doc Sizes.psp from folder: C:\Documents and Settings\USER_NAME\Application Data\Adobe\Photoshop\8.0\Adobe Photoshop CS Settings
Not working at all... any other solution to this problem?
Thanks
