Copying a selection of cells from LO3.5.0 to Postbox compose window (I guess it should be the same for Thunderbird) seems to send both program in infinite loop (CPU raises at 100%, no end time until one of the programs is killed). No such problem with LO 3.4.5.
I just noticed that this might be the HTML export that fails. Copying some cells from Calc and pasting them in a Writer document as HTML (paste special...) results in the same behaviour: 100% CPU... I haven't seen any problem when pasting in TextEdit (as RTF ?).
I can confirm the behaviour in the case that the CELL SELECTION CROSSES OVER HIDDEN COLUMNS: Copying this selection from CALC and pasting it into Thunderbird leads to hang-up of both LibO and Thunderbird unless CALC becomes terminated by Task-Manager. Then Thunderbird will be released. reproducable on Windows Xp SP3 with LibO 3.5.0 and LOdev3.5.2RC0-nightlyBuild-20120312 it does not happen in LibO 3.4.5
Freeze/Hang-Up of both LibO and Thunderbird if Copy&Paste-CELL SELECTION CROSSES OVER HIDDEN COLUMNS also happens in LibO 3.5.1 Release.
I'll take this one.
