i keep my finders with icon-only sidebars at 32x32...
see here. it stays this way in all my window that I click through the finder icon in the dock and drive icons from the desktop, but whenever i download a folder or make a new folder it keeps turning back to
this with the full sidebar and the bottom of sidebar a few pixels off. nomatter how much i keep resizing the sidebar and window, it keeps going back to that on the desktop... i remeber it used to be fine, but now it just annoys the crap out of me.
