Tooks me years to figure how to handle them correctly
I realize and appreciate that to the fullest.
That was a lot of work but that was the only way to complement the other controls in your aero skinning engine. All your GUIs are real beauties. You've got a rare combination of talents as an artist and software developer.
I guess a similar implementation of scrollbar in my relatively simple project would be too much, since that scrolling functionality can be mimic'ed with a much simpler means like those three trackbars that I'm using to adjust the aero params. I can use a similar vertical trackbar to scroll the text area, and in this manner I'll be able to reuse the existing code though of course it should be improved to some extent in order to make dragging more secure in what regards the cursor's permissible positioning while the trackbar thumb (knob) is being dragged.
Thanks for your advice anyway. Negative is also a valid result, and your hard-earned experience saved me
a lot of my time that would otherwise be spent on fruitless investigation of my own.
