[xsl] XSL & Popup Windows

I am generating a popup window that is linked to an xsl file rather than an
html file. The parent window itself is generated by an xsl file also. The
popup has a number of text and select inputs. For some reason, the text
inputs are not accepting any input from the keyboard and the selects are not
displaying their pulldown menus. When I try the same thing using a link to
an html file, it works - is there some peculiarity of xsl that could be
causing this?
