Okay, for the admins, here's what I know so far:
I'm using Mozilla Firefox, the most recent edition. I uninstalled, reinstalled, and refreshed the newest Firefox browser today.
I didn't install any ad blocking software on Firefox.
I cleared the cached web content from Firefox.
I overrided the automatic cache management and reset it from 350 MB down to 50 MB.
I then went to the Stromtroopers site and opened the reply window on three different threads in three different sub forums. In each case, the reply window loaded correctly, with all the word processing tools intact, no script errors, functioning emoticons, and no attachment list of all the photos from my photo album.
I then loaded Adblock Plus, and returned to the Stromtroopers site.
I opened three reply windows on three different threads in three different subforums. In each case the window did not load correctly; I received a script error each time; if I continued the unresponsive script window, I would just get the unresponsive script window again. If I stopped the script then the reply window did become active to the point I could enter text, but the word processing tools in the window were missing, the emoticons were inactive, and the long list of attached photos from my photo albums appeared on the attachment list.
I then disabled Adblock Plus (but didn't uninstall it), and tried to open a reply to a thread. I encountered the same issues described in the previous paragraph.
I then uninstalled Adblock Plus and began the thread reply that I am posting right now. The reply window loaded normally, with none of the errors previously described.
That's as much info as I have. I hope this helps someone guide me to a solution to the problem.
