Cheatin' Uh? When changing theme - w3TotalCache Compatibility

I have been dealing with, whenever editing a newsletter, a message of: Cheatin' Uh? If I changed anything while editing a newsletter, for example, changing the theme, I will get the message: Cheatin' Uh? and be forced to hit the back button on the browser to return to WordPress backend. I have determined it's a compatibility issue with W3TotalCache and was just wondering if anyone knew how to make these two plugins work together, or if there could be an update to work alongside this plugin.
