Well, you're probably not going to want to hear this but...
Has anyone else mentioned not being able to re-open the [Get More] if you open and close it while creating a message?
No - and I haven't had any trouble doing it. :-
Or not being able to put more than 2 "new" smileys on a post?
No - and I was able to insert the dozens of new smileys in my one post by clicking on them. :-
Or that the [Get More] window disappears and only reappears after I shut down everything else and I'm looking at the last blue screen before I shut the computer down?
No - how weird. :-
What might be happening here is some sort of conflict with your Java installation because the system uses a Java script to open the Smileys List window and to put their codes into posts. When was the last time Java was updated on your computer? If you don't have at least 1.4.0 installed, you might want to think about upgrading.
You can go
here to download an upgrade installation program. (1.4.0_03 is now available.)
But if you already have 1.4.0, it might still be Java related because the installation may have become corrupted. If you go into your Control Panel, double-click on the Java icon, and then check the box "Show Exception Dialog Box" and maybe you'll receive an error (rather than the Windows Blue Screen of Death, as it's "affectionately" know) the next time you try to do one of those things.
I know.....IE
It might be - but I was able to do all of the above in IE.
