new skin eliminates WYSIWYG editor

[subo]

Hi!

I've created an individual skin for our company. In Firefox everything looks fine but in IE9 the editor at "Tickets- New Phone Ticket" (and New
Email Ticket) disappears. (Shows up but disappears immediately)
This happens only in Internet Explorer (9.0) but not in FireFox (5.0 & 6.0 & 7.0.x).

Has anyone seen this problem too?

Greertings,
Subo
