I have a problem with imesser which I can't figure out how to fix or know if it can be fixed. Users browsing with either Mozilla or MSIE can have problems coming into chat, especially if they've left chat to browse other DNN pages and then try to return. But that may not be the real problem. It could be browser incompatibility or the use of DNN 4.8. If someone else has experience this, please reply here and tell me how you solved it or if it can be solved. Thank you.
