Elation II Pro fixtures will either lock up or cycle thru gobos after cue updates, HELP?

During a service/show (Church), one of our Elation (Platinum Pro II) fixtures will lock up. Cannot Reset/Control for minutes and I can't re-enact the possible cause. It is not one specific fixture, we have 10, and they each go thru this at random times. It gets really frustrating when a guest is in the middle of Worship, and a light is shining on them, and there is nothing I can do until it eventually resets itself. Is this a known issue with the fixture's themselves or is it the Console (Road Hog4)?
Same fixtures, theres another problem while programming, when updating a cue or making any changes... after hitting "Enter" the fixture's gobo wheel rolls on their own. I have to re-initiate the cue to get the fixtures back to their intended Gobo.
Hope this all makes sense and there is a reasonable explanation. Are there any solutions? Thank You - Tim
