try running an external bec. I was having this problem with the MM too, until I went with the external bec. I don't have any technical details to refer too, but I suspect that the internal bec on the MM isn't the greatest. I believe that what you perceive the be glitching is the internal bec cutting current to the radio for a split second, the rest of the non response time is due to the radio rebooting. Try the external bec. The one that Mike sells is nice, but if you are on a budget, there are a bunch of linear becs that can be had for $10-$15.
