Team, I am working on Bug # 1520 on sugarlabs. <a href="http://bugs.sugarlabs.org/ticket/1520" target="_blank">http://bugs.sugarlabs.org/ticket/1520</a> I tried to reproduce the issue on sugar-emulator. I realised that Alt + Tab did nothing. Instead, Alt+Tab functioned for GNOME. I tried to run sugar from sugar-session. Still, Alt+ Tab did nothing. Firstly, I would require some pointers on how to reproduce the bug. Secondly, when I read the comments on the bugs page, I realised that fran pointed out that this functioning of the Alt+Tab as mentioned in the bug can also be considered as a utility rather than a bug. A very similar bug to bug #1520 is #1518. <a href="http://bugs.sugarlabs.org/ticket/1518" target="_blank">http://bugs.sugarlabs.org/ticket/1518</a> As far as solving the current bug is concerned I realised that Bernie had created a patch for the same in fedora and that could be implemented on ubuntu. I have studied the patch - <a href="http://sascha.silbe.org/patches/metacity-ungrab-keybindings.patch" target="_blank">http://sascha.silbe.org/patches/metacity-ungrab-keybindings.patch</a> Regards, Mukul Gupta Research Engineer, SEETA
