Compose a new MailNews message in AutoDetect or Rich Text modes. 2. Starting from Abiword or Open Office, select text or tables, and paste them into your message. Actual Results: Undo won't get rid of the new text or tables. And often the formatting of the message changes in a way that "discontinue text styles" won't fix. Even switching the edit mode to plain text won't get rid of the fonts or styles applied. Expected Results: Undo works. "discontinue text styles" works. I can make you a video tape of this happening. It's happened for years -- this is not a new bug.
When I paste a table from OpenOffice Calc, I get ###!!! ASSERTION: JoinNode called with node not listed in offset table.: '0', file mozilla/editor/txtsvc/src/nsTextServicesDocument.cpp, line 2630 (1 of those for each cell) When I try to undo, I get: An error occurred executing the cmd_undo command [Exception... "Node was not found" code: "8" nsresult: "0x80530008 (NS_ERROR_DOM_NOT_FOUND_ERR)" location: "chrome://global/content/globalOverlay.js Line: 86"] Based on that and bug 290261 comment 4, this might be a dupe (if composer performs the paste by setting innerHTML), but I'll leave it open for now.
two seperate testers one with Linux/KDE (with paste from libreoffice) and another on windows, say its WFM.
