Hi 4cassandra, I’m very sorry you’re having these troubles. When I test with Chrome I don’t experience these problems, but I do understand that these issues exist on some computers.
There are many things that can be tried to fix these types of issues including the points set out here: http://blog.ribbet.com/?topic=trouble-loading-ribbet I would suggest clearing your cache [step 3] as a possible solution (so that Ribbet is forced to reload).
Unfortunately Chrome sometimes seems to not behave correctly with Flash, and I have seen some suggestions on fixing this such as in this article: http://www.pcmech.com/article/problems-with-google-chrome-and-shockwave-flash/.
If you do resolve the issue please let us know what worked for you. Sorry I can’t point you to a simple and certain fix.
