Sometime back I had a issue with the scroll bar shown in the webBrowserComponent, since it used to show the OS-specific scroll bar which used to stand out in my application.(my applications loads pages from our web-site)
It was manageable on windows since Internet Explorer allows scroll bar Customization, but Macintosh was a problem. Came across this
it allows customization of scroll bar on FireFox, Safari and Internet Explorer . And it’s free.
