Some OLE objects are editable in LO in a way with is rather destructive. Example: PDF documents. When one: 1. Adds a PDF document as an OLE object. 2. Right-clicks, and chooses Edit on the context menu It would be useful it LO would warn the user that editing the PDF may result in degradation of the document regardless of concrete changes the user makes. No additional warnings need be give on repeated edits Bikeshedding I: How do we decide which formats are "safe" to edit with no warnings? Bikeshedding II: Should the warning be given once per object? Once per (LO session, object)? And there are other options even. Note: If such a warning is made, then the significance of bug 160949 decreases somewhat.

Filed as bug 160962; but that's a different issue. > Other than that I could imagine a solution per frame/section that is made > read-only. No, I mean for content that is _not_ read-only nor protected. Novice users will not realize that the mere act of opening some OLE objects for editing - changes them significantly, possibly degrading them.
