Hi, I just joined after a month with my new Blackberry 7100G, which was a "gift" from my office

so they can keep track of me every second of the day. I run our intranet website for a large division of our business and one just never knows when something will crash and I have to summon the appropriate folks to get stuff working again.
I bought the Blackberry for Dummies book and have learned lots, however I just discovered something I can't quite figure out.
I'm trying to access a website which requires a password. (Hope I can explain this properly...) When I typed the password (or try to anyway), let's say my password is
viknf
So when I press the CV key, a C is displayed in the password field, which immediately vanishes as the * conceals it. However, I don't want the C, I need the V. Get my drift? I hit the DEL< key which in any other application works fine, but the C continues to display, rather than the V. It's like it won't recognize the second letter/option available on each key - I can only get the first letter on a particular key to show up.
What am I doing wrong, and nice to "meet" each of you! I look forward to learning lots here, and hopefully being able to give something back one day.
