UI Slider - IE6 Disappear

UI Slider - IE6 Disappear

I'm using jQuery's UI slider plug in and there are a few problems in ie6.

I can click on the slider handle and move it around, but when I release the mouse button, the slider handle disappears. When I press the mouse button again, the handle reappears until I release the mouse button.

Anyone had a problem like the before?

Any ideas on how to solve it?

Thanks for any help you can provide,

Joe
