I can confirm this issue occurs under Hardy Heron x86_64 running Gnome+Compiz, with ED2k Hash Builder by HiEv. If the application is minimized, or placed in the background 'behind' other windows, it vanishes, becomes inaccessible, and can only be closed by killing it within System Monitor.
It does _not_ happen with Irfan View, Power Poat A&A, QuickPar, or DVDFab HD Decrypter. -- Taskbar buttons missing in Wine 0.9.59 https://bugs.launchpad.net/bugs/216235 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
