I am also having an issue with pasting in LibreOffice on MAC OSX 10.7 with LO 3.5.2.2. It seems that whenever I copy from within a cell in CALC, it adds a carriage return to the end of the string. I.E. Click on cell containing asdfghjk, highlight cell contents “asdf”, command + C, then in TextEdit, Command + V, Command + V…it doesn’t paste as asdfasdf it pastes as:
asdf
asdf
(except together with no extra line in between…formatting on this forum is funky)
For the issue you are having, I am able to use regular paste within a spreadsheet document and it retains its cell properties. I did notice however, that when I opened an excel file in LibreOffice and copied from it into a new ods sheet that it lost its formatting.
If I used “Paste Special…” and checked Paste ALL it seemed to resolve the issue. It’s still a little frustrating and tedious when you are copying a bunch of individual cells.
As far as all the issues you are having, I am not able to replicate any of them. Are you using protected documents or files loaded from a different file format, or did you try this on a brand new sheet?
You can also try installing the 32 bit version instead, maybe the 64bit build is off…
