Hello Cecil,
I am using both opera and mozilla firefox.
For Opera, whenever I want to reply and quote your response, I could not drag your quote into the message box. When I click "add quote box" and "quote text," nothing appears. In short, I have to cut and paste your quote to the message box.
For Mozilla, whenever I want to reply and quote your response, no quotes appear for me to drag them to the message box. So just like Opera, I have to cut and paste the quote to the message box.
I wonder what's wrong with my browsers?
Anyway, this is just FYI.

Please note that the forum "software" does not reside on your system. It is like a web-based application. And we have some constraints and limitations in the use of it.

Thus, since users don't often post that often, then try using "cut-paste" feature.

Frankly, I do often reply on-the road with either my Sony models: UX or TX notebook pcs and the problem lies with my "voda-phone" modem = Singapore M1 provider. And Robert, had a worked around just for me. And because of this, we are not going to implement what you had mentioned. Thanks for your understanding!
