IT WORKS! Thanks Zamiel. Between your instructions and JeffJ I was able to get a fully functional Opera browser in Midori m4i-2.3pre1 with the dial-up modem.
Just to be clear, in my case it required two workarounds from the normal configuration.
Problem (1): Username does not allow "@" symbol. (I.E., you can't use your email address)
Step 1) Enter your information into the (modem setup) area and click "Save".
Step 2) Run the built-in editor Nedit and drill down to //tmp/config/.eznet/eznet.conf, open it, add your "@" and save it back out.
Step 3) Click back to Opera and under (Storage), Freeze the configuration.
Problem (2): DNS numbers are not working (address' are not resolved)
Step 1) Open the editor Nedit and drill down to //tmp/config/etc/resolv.conf , open it, add your DNS numbers as:
then save it back out.
Step 2) Click back to Opera and under (Storage), Freeze the configuration.
Also, I noticed that any bookmarks made during a session are not saved unless you "Freeze" them before you shutdown.
