External css linkage problem in Safari

[isplice]

Linking an external layout css to my page seems to break my scroller intermittently in Safari only. All other browsers seem to handle the linkage fine. It happens most often when using the back button but also when going from page to page. When i leave the style in my header everything functions fine.

Examples:

jscrollpane not functioning when linking external css "contentpage2.css":

Any thoughts on this really appreciated.
