Motorola Xoom :: Can't Type In Certain Fields

I have been having problems typing text in some fields. In certain forums, and on some sites where I am asked to input data, the keyboard appears, but when i type nothing happens. I did some playing and found out that although nothing appears to be entered, the text is in fact entered, just invisible. have password text set to visible in the settings, so that isn't it. And in most applications the text entering works fine.
