Style=dashed blurs when scrolling

[internetheaven]

I use the style="border-top:1px dashed #535353;" on my site but if I use my mouse wheel to scroll up and down on my browser the dashes become blurred and missing. If I use the scrolling bar on the side of the browser though the dashes stay looking great.

What causes that and is there any way around it? (only happens in IE, Firefox is fine)

I don't know IH, but IE does have numerous redraw anomalies perhaps this is one of them?

You haven't posted any code and I can't reproduce it with a simple single paragraph scroll test, perhaps if you can post some simple code which demonstrates that you're seeing we can narrow it to a cause or not ;)
