I've searched the forum to no avail... just installed SR4 and previously fine pictures are now rendering with a grey strip down the size and the background picture 'squished' into the remaining space. BG pic looks fine while I'm editing - right size and no grey bits but when I render its all squished up. Its not a problem with the pic not matching document window size - these DID render fine pre-SR4. And annoyingly, SR4 limits the size of a background pic to 4096px. Grrrr. Any help would be most gratefully appreciated. I'm not usually one for asking questions but I can't find any info on this and its driving me nuts! Steph
