Endless Paradigm

ive been trying to create a theme but have been having some trouble.
ive relocated the xmb and for some reason when i go into say the music or video the xmb icons vanish or get relocated somwhere else.
i know its proberly a noob question but i have just started tryin to make themes
could someone please just explain to me why this happen and maybe give me a few pointers?
cheers

you postioned soemthing wrongor the icons you are usinga are too large and they don't display due to resource limitations.

need more info

when i change the xmb icon position do i need to change in vshmain and topmenu-plugin
or just one and how would i go about keepin the icons in the same location when i go into say the video setiings or theme settings

thanks

also would it be possible to make the sub icons appear in the exact location as the main icons?
