1. I work on a document, export it as a PDF, it's exactly how I want it. I close the file. The next time I open it the page layout has changed, somehow, somewhere in the document lines have been pushed over the page and the pagination is out. Weird
2. My Mac is a fairly recent one with lots of RAM and processing power, I never have difficulty with any other program not opening files, not being able to work with files &c. .sla files over about 500k are very slow to open and edit, like I will wait 5 minutes for a file to open, it takes 1 minute to go to certain page, if I edit the keystrokes take 20 seconds to register &c. I have one file over 2 megabytes which takes hours to open and is so slow that it is uneditable. Surely Scribus should be able to handle large files, what about publications with lots of graphics?
Any advice on either problem gratefully received.
