Whats the point of using XCF files when the undo history isn't saved? I can save in Tiff format and get exactly the same amount of information back when I reopen the file. Anyway I loose the undo history. I thought the point of using XCF files was that ALL information INCLUDING undo history was saved with the file. The way it works now, I have to save under different file names each time I open the file and make some changes. If not, all possibillities of undo is lost. Trond.
