In the print setup/scale-view/drawing units I mark the milimeters. Saving the file, closing it , reopening it this setting is changed in inches. It must have something to do with the fact that my layouts are screwed up every time I reopen it... ? Recovering a file sometimes seems to solve the "saving invalid data" problem untill I touch the layout button, I get an unusable layout , whatever I try to change , F.i. creating a new layout which is ok then. The "invalid data" message reappears when saving.
