My laptop/tablet's touch pad has a feature that running your finger along the right edge will scroll the current application. It's scroll indicator comes on indicating it thinks it's telling the application to scroll displays, but no scrolling actually happens in Logos4.
Also the Drag Up/Drag Down gestures on the touch screen likewise display their indicator that they are telling the current app to scroll one screen up or down, but no scrolling actually happens in Logos 4. The latter seriously effects one's ability to use Logos4 on a tablet (i.e., without a keyboard). While the gestures can be reconfigured to do page up/page down keypresses instead, this is unacceptable as other document applications (such as acrobat reader) will move to the next/previous physical page of the document, which may be more than one screen full of text away.
Given that the appearance of the scroll bars is so different from the standard scroll bars, I'm guessing you "rolled your own". Please eather fix your implementation to respond to these types of scroll events, or please give us the option to use standard scroll bars.
Speaking of the scroll bars, I dislike how they kinda grey out when you aren't hovering over them. I would prefer that they stay visible. I also don't like the rounded shape of the thing you drag to scroll. I prefer my Windows applications to look like Windows applications with a nice squared off thing.
