The same thing used to happen in MS Word and either PowerPoint or Excel 98. You could delete half the document and it would STILL grow by 10k or however much. Disabling Fast Save resolved the issue.Viro said:I remember such an issue back when using MS Word on Windows (no idea if it applies to Word on OS X). Disabling the Quick Save feature helped. Perhaps there is something similar for InDesign? Quick Save was a feature that caused only incremental differences to be saved, and I guess other stuff like time of change, etc were included hence the bloat.
