Losing Fixtures (homing up)

I just setup a show with the new software 3.0.0 and as I was wringing out the system I noticed that I would have to grab and shake some fixtures before they would "Home" down. At one point I went away for about an hour and when I came back about half the rig was homed up again. The units immediatly find themselves if either pan or tilt is touched. Is this some kind of DMX hickup I am getting with the new software? Nothing else on this system has changed so I am not sure what else this could be.

I am using a Whole Hog III with Playback Wing and 2 External Monitors and a DP 2000 with the following fixtures patched;
12 Mac 2k Profiles
12 Mac 2k Washes
12 575 Studio Spots
12 575 Studio Colors

This problem is not isolated to any one type of fixture. I am routed through an Iso Splitter on each of the three moving light universes in the DP 2000 but I have never had this problem with this system before. Any suggestions?

    Here's a couple of thoughts. If the the fixture was losing data then instead of going to position 0/0 pan/tilt it would most likely just stay at 50/50 pan/tilt and eventually douce the lamp. So I think we can rule out a loss of dmx. Instead it sounds like we are dealing with the fixture explicitly being told to go to 0/0 pan/tilt which would be a dmx value of 0 for those channels. So, to confirm that the board is actually sending this value it would be best to open the dmx window (setup, dmx) and check to see what the actually dmx output values are from the board. Since all of your fixtures are going to 0/0 pan/tilt you should see tons, if not all, 0s as values in the dmx window.
