Windows 7: Mouse Middle Button and scrollbar doesn't scroll Folders on List view

Dunno when it happened, months ago, but on my Windows 7 64b folders my middle mouse button and the arrow at the end of the Scrollbar doesn't scroll to the right when in list mode.

In Details View, Large Icons View, etc the scrolling works up/down properly, only in List View which is left/right it only scrolls to the left using the mouse or by clicking on the left arrow on the scrollbar. So the only way i have to scroll to the right in a folder on list view is to either navigate the files or use the bar on the scrollbar.

This is super annoying since my preferred view is list.



If anybody knows of a fix please share.

Thanks

Well have you installed any sort of explorer tweak or shell in the past that might have interfered with the default behavior?
Else you should try some registry fixers because it seems like this is either an issue with your register or with the "explorer.exe" application.

I don't recall doing any tweaks that would mess with the explorer, but this has been going on for months so i can't be sure.

I did try registry fixer, but did not fix. Maybe I'll see if i can find a explorer.exe from a windows install dvd or something and replace mine with it to see if it fixes it.
