I have the free version of the newest XiiaLive (3.0.0.02) and, along with the previous update (which was my first install of XiiaLive), I have been unable to seek on any AAC+ streams. When I slide the seek bar, it sticks for a second and then snaps back to the current position. Everything else works fine (including seeking on MP3 streams). This is with the stream engine set to "Android".
I use a Fujitsu F-10D (Japanese market) phone. It uses a Tegra 3 processor and ICS.
(Edit: I can't seek with ANY program if I change the stream engine to "FFmpeg." I'm not sure if thats just because its a new feature or not.)
