Version: 1.5.6 (using KDE KDE 3.5.6) Installed from: Fedora RPMs OS: Linux When I switched desktop, my umbrello document is marked as modified. I occurs when I switch with keyboard shortcut or via pager. It's pretty easy to reproduce, open a new document, add a class, save it, switch desktop et voila. $ rpm -q -f /usr/bin/umbrello kdesdk-3.5.6-0.1.fc6
This behaviour has been fixed on the current version (trunk).
