occasionally, I get into a state whereby hitting the hard home key doesn't bring the launcher7 UI up. There's an audible click response, but the display doesn't change from the currently loaded app. Once in this state, I can only return to the launcher7 screen if the app unloads itself (e.g. by pressing the hard back key often enough).
Phone is an HTC Desire A8181.
Android 2.2
Baseband version 32.49.00.32U_5.11.05.27
Kernel version 2.6.32.15-gfa401c
Build number 2.29.305.5 CL293415
Launcher version 1.0.1.17, but problem was also present on previous version.
Hmm, this is certainly strange. I have never heard of such an issue. Nonetheless the developer of Launcher 7 has been informed, and thank you for providing such verbose information!
I've done some controlled testing (reluctantly went back to using the HTC sense home screen), and the bug has started happening again - must be some other app causing problems.
