That forum page opens a rich text editor (i.e. not a plain text editor like used on this forum). Doesn't that editor are open for you if you click the reply box ? Does it work in a New Private Window when you aren't logged in ?

Aha! Clearing the cache fixed the problem. Thanks so much!

Glad to help. Safe Surfing.
