Oh, and I installed mkvtoolnix via ppa from the developer's website: http://www.bunkus.org/videotools/mkvtoolnix/downloads.html
Still happens, no matter which version of mkvtoolnix I ever used. It's a problem of those overlay scrollbars. I experienced it in other applications as well, no matter if a fresh install of Ubuntu or not. However, mkvtoolnix is the application I remember at the moment after I experienced it again today. There is also a sometimes problem of horizontal overlay scrollbars covering buttons that are below in case those buttons are very close to the scrollbar area. Those buttons then cannot be clicked. However, I can't remember which application it was where I experienced this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1103014 Title: Impossible to grab scrollbar handler in wide dropdown menus To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/overlay-scrollbar/+bug/1103014/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
