forced apps rotate in my case only works in these circumstances:
1. when i've unlocked the screen in portrait mode.
2. when in conversations, fastsmsevo pops out.

besides that, after a reboot for example, it doesn't force them to rotate on it's own. i'll have to do one of the above and then the apps will rotate automatically... all except for the ones that already rotate on their own and the apps launcher... apps launcher rotates all the time...

also, when rotating, there's a half a second of blinking...

hope this helps
