The fly-over messages are generally controlled by the browser. Firefox and a few other browsers leave the popups visible until you move the cursor off the graphic. IE displays them for four or five seconds and then takes them away.

Another enterprise customer raised the same issue a couple weeks ago. In response, I developed some code to have Amion generate the fly-overs so that they don't disappear even in IE until you move the mouse to another location. I also made the text in the popup a little bigger so that it would be easier to read.
