[edit]problem fixed[/edit]

The customized search bar in IE6, you cannot enter any text (maybe you can, but can't see it)

There's no cursor when you type

Not sure what the problem might be? Maybe IE6 not being able to handle input classes

i couldnt see any problem related to ur issue,

This is an issue with all browsers. You see it better in IE6.

labels and felements have different top margins attached.

In the moment you have something like:
.fitem label { margin: 0; }
.fitem .felement { margin: 5px 0 0 10px }

When you set the same top margin the elements align ok.
