I have been using Mezzmo for the last year or so on my combination wired / wireless network. In addition to a Samsung TV and an xBox 360, there are several laptops running XBMC 11.0. I have recently noticed that when playing Mezzmo based movies with XBMC, I can no longer control the "progress bar" (the horizontal bar at the bottom with the slider that moves from left to right as the file plays back). If I try to drag the slider to a new position (forward or backward), it simply snaps back to the earlier position as soon as I release the mouse button.

1. This problem did not occur with XBMC v11 and earlier versions of Mezzmo.
2. I first noticed the problem after installing Mezzmo v2.7.1, although it could have been introduced earlier.
3. This problem does not occur when playing the same movie files with XBMC 11 directly.

Is this a known problem? If so, is there a fix or workaround?

All help appreciated. Thanks.
