R – sIFR Mouse over styles and Scrolling Issues on Windows OS

I’m a windows OS user and use sifr3, I have some issues.

I. MOUSE OVER STYLES:

I have set color, hand pointer style, for mouse over.

firefox/safary:

After I scroll up/down a little by scroll bar in the browser, then I do mouse over on the embedded letter, but I don’t see the style I have set for mouse over.

II. SCROLLIING:

firefox/safary:

When I do mouse over on a letter I have embedded and scroll up/down by my mouse; then the scrolling is not working.

some other (google chrome/ IE7):

After click on the embedded letter, I cannot scroll by mouse too.

And I have tested with some sites that use sifr3, such as:

  Note: It may have problem only in Windows OS.
  

Any one help please?

Best regards,
