That's due to the somewhat confused signal handling. Sadly however, I don't have an opportunity to fix it. I have to apologize. Uli Thank you for your bug report. The bug that you reported has been identified and has been fixed in the latest development (CVS) version of KOffice. The bug report will be closed. |
