I'm getting so used to JavaFIBS that I'm not missing MacFIBS so much any more. However, there are two minor frustrations I have with leaving messages:

- It'd be great to see a copy of the message you've just sent after sending it in case you've forgotten something or have a major typo

- With long messages I can't see what I'm typing because of the resizing tab in the bottom right corner covering the last character (might be different for others, but this is how I see it with Mac OS 10.2). It's also an issue for long shouts, kibitzes, etc.

Messages do work much better with those on your friends list, but often I have to leave messages for arranging tournaments and don't want to have everyone on my friends list!

This really is a minor nit pick, but that just reflects how good JavaFIBS is overall    

You can cut and paste in java - so i type my messages in the long line at the bottom - used for kibitz - then cut and paste into message box - you can check for typos that way - and see it more clearly - also when you send the message - if you have the system info on - the message shows there - as it will appear on your recipients screen. (the cut and paste is the control c, control v method). You can also add the person to your friends list - message them and then remove. Overall - java is soo nice i just find ways round the teeny issues    
Dont know what you mean about resizing tab though - i dont seem to have one of those obscuring anything on my screen.
