Please help, opera mini problems

[willpower101]

So i downloaded opera mini 4 which runs in the java environment and it's being weird.

When I try to search this site, the box drops down, but I can't enter text. When i try to click on the text field or the advanced link it treats the whole box as a link and reloads the page. Any idea what's causing this and how to fix?

Also, is there any way to enter the text directly into fields like this one, instead of having a giant white window pop up to take the entire screen? It even does this on login fields and the address bar and it's pretty annoying.

Last but not least. It freezes to the point of needing a reset too often. Usually it happens after i've spent a few minutes doing something like entering this message here.
