I commented on scroll bar problems in OSX in an earlier thread. (side comment: does anyone ever read/reply?)
Doesn't anyone in the dev team use a mouse?
I have to ask, because the non-standard scroll bars make life difficult for mouse users. On OSX they're too narrow, and it is too easy to hit the right border of the window and drag it instead of scrolling, even when maximised.
On Windows, the scroll bar is over/under-written with marker lines, and text overwrites the track. Again, the bar is too narrow for the user's Windows settings.
Is this ever likely to change?
