Yeah, thats what I mean. It's basically almost impossible to see unless you mouse over it.
I'm not sure why you'd want a highly visible scrollbar there without being able to see how far scrolled you are to be honest, surely there's no point at all to having a scrollbar visible if you can't see the amount you've scrolled or have left to scroll? Wouldn't it also make MUCH more sense to allow the user the option to make the scroll point near invisible? I frequently look at the scrollbars for different reasons to see where I am in a document or something. You may not do it yourself, but removing an option for this isn't smart, by anyones standards.
Just to give an example, if I'm looking at a document which has around 500 pages and I'm on page 425 and need to get to somewhere around page 170, would you honestly sit there and scroll wheel through that many pages when you can just grab the scroll bar and move it almost precisely where you need to be? If you got linked directly to page 425 and didn't know how many pages the document had, the first thing you would do is look to the scroll bar to get an idea. Both of these are just two examples of why not being able to see the bar is a massive pain the the behind, something I wouldn't even need to mention if the option was there to be able to see it properly :/
