Overlapping Status Messages During Install Dialog

On the actual Installation dialog, sometimes the status messages that flash by don't delete. Normally there is a message written above the loading bar that is deleted as soon as the next one is shown. However on some installs the messages never delete, and just write over top of each other until there is a mess of text displayed there. Sorry if I'm not describing this well. I've attached a screen shot if that helps.



I have no clue how to fix this. Has anyone else seen this before?
