I am working in Calc with multiple windows open, one of which is on a second display. When I select some rows and move them to other empty rows, Libreoffice (v 4.4.7.2) crashes and upon opening again, it 'retrieves' my documents, which seems to be a fancy word for just loading my last saves. This problem occurred several times now and I am a bit reluctant to update to v 5, sinc I hear it is less table than v. 4.4. and this one isn't even stable to me. I run Mac OS 10.11.3.
Created attachment 122349 [details] error log of crash
I'm unable to reproduce this behavior with the same environment (OSX 10.11.3, LO Version: 4.4.7.2). I attempted opening a 234KB csv file and shifting around the cell contents between my MBP screen and external monitor and cutting and pasting between the two screens without crashing.
2 things you can do: 1) rename your LO directory profile (see https://wiki.documentfoundation.org/UserProfile#Mac_OS_X) and give a new try 2) try last stable LO version 5.1.4 At worst, you can uninstall 5.1.4 and install again 4.4 version.
