Thanks for the reply. You are right. I was looking at changing the ui flow based on how the code was reacting to user input. I've downloaded the twitter code and am taking a quick look. It looks like it used the classdesigner and the menudesigner which I did not think was working from something I read somewhere. At the moment it gives me an invalid XML string when I try to run it or load it into the classdesigner. Regarding dPanel, you are probably right. I got so far in looking through code to see what was going on and then stopped for a breather. I'll look at dApp and see how I turn off the default menu. I'm not too fussed about the font sizing problem for the moment. I just thought I would mention it as part of the issues I had so far to see if it was a known problem or just something I had falled upon.
