<div><font style="background-color: transparent;">I am just starting to introduce Alice at a new school. We will only have a few sessions with it. I am hoping to introduce it to them, so many will be sparked to work on it/play with it over the summer on their own.</font></div>
<div>Anyway, upon first launching it, it gave me this Unknown Error Has Occurred. I haven't ever seen this error in the others schools I've used Alice.</div>
<div> It seems like it maybe a Java error?? Will we have more troubles as we create Alice stories?</div>
