I do, but it's not Jetbrains' fault.
If you want better scrolling support, you need to vote for this bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6440198
I am sick of having to scroll log panes etc. manually. Especially since I've had mice that support this for literally years.
So if you would also like to make your life a bit easier, go vote for the bug and maybe then we can get the functionality in IDEA.
Also, does anyone know if it's possible to make IDEA scroll horizontally with the keyboard? (or perhaps with SHIFT+scroll)
