Milonic JavaScript Menu

Combining top offset with scrren position works fine, BUT it makes the menu unusable because of the flickering it produces. I don't know why? Because of the image and overimage commands? Try:

with(menuStyle=new mm_style()){
bordercolor="#000000";
borderstyle="solid";
borderwidth=0;
fontfamily ...

I got why it doesn't work, but it's still a problem.

'Followscroll=10;' works fine alone, but when you add 'screenposition="center"' it makes the value of followscreen equal to zero! Try:

1) This works (it's as in examples):

with(milonic=new menuname("Main Menu")){
alwaysvisible=1;
followscroll ...

This sets only the position eg 10 pixels ONLY AT THE TOP of the page like this:


*TOP*
10 pixels here between top of the screen and menu
*MENU*


But when you add followscroll and make it follow you down the page, the menu will move and stick at the top (=0 pixels) on the screen like this:


*TOP ...

I can't manage to set my follow scrolling menu top start position 10 in pixels.

I tried:
followscroll="10";
followscroll='10';
followscroll=10;
Neither worked. All I get is always top start position = 1!

However follow scrolling menu in examples work properly.
What should be the exact line of ...
