What operating system are you using?
Oh forgot to mention that, Windows 7 x64
Actually i found two different save for web preferences on windows 7 for cs6, each a different file size.
(on older versions cs4 and before one could reset the save for web prefences by holding down Ctrl+Alt
while starting save for web, but as far as i know that was removed starting in photoshop cs5)
C:\Users\Your Name\AppData\Local\Adobe Save for Web 13.0 Prefs
C:\Users\Your Name\AppData\Roaming\Adobe\Plugins\Adobe Save for Web CS6\Photoshop\Adobe Save for Web CS6 Prefs
Actually I deleted the file at:
C:\Users\<User>\AppData\Roaming\Adobe\Adobe Photoshop CS6\Adobe Photoshop CS6\Recently Used Optimizations.irs
And that seems to have reset the Save For Web settings... thanks for the help though.
