I too can confirm this bug with dia-gnome 0.97.2-5 on Ubuntu 12.04.3 (amd64).
I did however find another workaround - from http://osdir.com/ml/dia- list/2013-09/msg00034.html - whereby starting Dia with an environmental variable set to disable Ubuntu's overlay scrollbar does seem to stop the unwanted behaviour. Therefore it would appear to me that this bug could well be down to an incompatibility between Dia and the aforementioned overlay scrollbar ('overlay-scrollbar'?). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1011446 Title: UML drawing tools' comment fields are too small to be usable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dia/+bug/1011446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
