Did you cut and paste it into the box or type it in? Recheck it. If it still does not accept it, then there is a gremlin in the garden. Simple pm Dennis and ask him to check it for you. Supply your ICQ ID and then he may be able to put it in whilst he is checking the bug report.
There is still a lot of background work Dennis is doing to iron out all of the bugs. The bugs will only get ironed out if he knows about them, and it is wonderful that everyone is giving him a heads up...
when they find bugs.
Hope that helps.
