hi xoozlez,

Sounds like you have an issue with your css. I believe position:relative is dependent on the containing container, have you tried using position:absolute or position:static. It all depends on how you've coded the skin up and the accompanying css. Do you have a page up and running on the web that I could look at?

A great tool for checking css is firebug which is an add on for firefox well worth downloading and it is fab for finding problems like this.

Hi xoozlez

I had exactly the same problem - a nice css skin with no tables and fine in all browsers but the .ModuleTitle_SubMenu is offset down by 100's of pixels.

I should point out that this is my first css skin and I had been learning about positioning css. I found that I was being too complicated and had applied attributes that I did not need.  I had been careful (as i thought I should be) about adding a relative attribute to divs as required. 
I found that removing these solved my submenu offset problem.

Hope this of some help to you.   I am very happy as I have had almost 12 hours on this.

BTW: If you look at the default MinimalExtropy css it is noticeable that positioning css is mostly applied to elements within divs and not the divs themselves.
