I had clock application running, and went back to task switcher to close another open application. After closing the other application I ment to go back to the clock application, but tapped the background accidentally. I quickly tapped the clock thinking that I didn't make it in time and it would go to desktop, but after all it did open the clock.

But it's somehow messed up, the clock seems to look like it shoud but the titlebar is weird, it is only black bar and the interface (the whole screen) does not accept any input eventhough the tap sound comes from speakers. The only way to recover from that, is to either open the camera or use the power key menu and open the phone. After that everything is back to normal.

For me this behaviour is reproducible always and with every application. The too quick tap to background and then to a open application always gets the interface stuck.

I'm guessing that this is a bug? I tried to make a quick search from bugtracker and from these forums, but didn't find anything related to this. If someone can confirm this described behaviour and this is not a know issue, I can post it to the bugtracker.

i came accross smilar issue about 4 times. system becomes unresponsive or very slow but i dont know exactly how it happens.

it usually happens after the reboot. once happened when i got a incoming call as soon as phone started

Confirmed - I can produce this behaviour too, though you really do have to click quite quickly. Can anyone with PR1.1 give it a try?

You can also get it back to normal by pressing Ctrl-Backspace: the launcher menu button will appear and then you can simply click on the application and input will be refocussed.

Reported the bug.
