Hi all, I am working on the bug: <a href="http://bugs.sugarlabs.org/ticket/1520">http://bugs.sugarlabs.org/ticket/1520</a> I was unable to reproduce the bug because the 'Alt + Tab' function doesn't work in Sugar on Ubuntu (Neither in emulator nor in Sugar-Session). I had a discussion on this with Aleksey Lim. He suggested using the command in Sugar-session 'metacity-message disable-keybindings' and then try the combination 'Alt+Tab'. But unfortunately that also did not work out. (No pop-up came) The problem with sugar-emulator: Somehow the native X sessions' priority is higher then Xephyr's. So even if the function for 'Alt+Tab' is coded into Sugar. The emulator (on Xephyr) still won't be able to catch that. Aleksey suggested we have to disable the 'Alt+Tab' combination in Sugar-Emulator. It would be great to have some views and pointers on the above situation. Is there any way we can implement the 'Alt + Tab' in Xephyr too? Regards, Dipankar
