I already posted this in Apache Bugs with no answer. I was wondering if anyone experienced a similar issue, since this is really a crucial thing that reduces working properly in Appache Open Office Writer for me

Here's my the description:
Scroll bar in OO-Writer doesn't show a bar to move with the mouse, scrolling only "blindly" possible. Seems this is a graphical problem, since scrolling itself works. Also appears in other OO-programs (Calc etc.).
System is Ubuntu Quantal 12.10 with AOO 3.4.1.
Hope ta hear from u, Felix
