FF - ok, IE - nefunkcnost java scriptu

Na stranke vyuzivam
1. dock menu, ktore vyuziva interface.js a jquery.js zo stranky: http://www.ndesign-studio.com/blog/mac/css-dock-menu
2. formular, ktory vyuziva fValidator.js, mootools.js, iMask.js a shCore.js zo stranky: http://zendold.lojcomm.com.br/fvalidator/
V Opere a Mozile funguje vsetko tak ako ma, ale v IE nefunguje ten formular. Neviete v com by mohol byt problem? Da sa to rozbehat tym, ze ten formular nacitam do iframu, ale to nie je stastne riesenie. Pomozte mi prosim.
Takisto to ma problemy s lightwindow zo stranky:
