There are a couple of issues I'm having with CuteChat at the moment:

1. The embedded chat mode doesn't work in Safari. I can get CuteChat to work if I use the direct URL (i.e. "/CuteSoft_Client/CuteChat/CH_MainForm.Aspx?Location=Lobby&LocationId=1"), but I get the following error when I try to load my own page in embed mode:
   
   Disconnected , Error : Value cannot be null
   Parameter name: location
   
   The page works fine in IE and Firefox - I only get the error in Safari.
   
   
   
2. Contextual menus go all wacky in Firefox when using an XHTML DOCTYPE. They work fine using the default HTML 4.0 Transitional DOCTYPE, but if I switch to XHTML, all new menus appear in the bottom left-hand corner of the page (instead of where the mouse is clicked).
   

Any ideas on how these issues can be resolved?

Ok, I managed to fix my problems. If anyone's interested:

1. It seems that the querystring gets added to the URL of the embedded flash file when using Safari. Adding "Location=Lobby&LocationId=1" to the end of the embedded page URL will get the chat working again. Alternately, you can edit EmbedChannel.ascx so that these values are passed on to the flash file.
   
   
   
2. I got around the menu issue by detecting whether a Mozilla browser is being used and then serving it a HTML 4.0 DOCTYPE instead of the XHTML. It's not ideal, but it works.
