If I open a file in the VS2010 IDE that causes the solution explorer to expand a file tree, then the scroll functionality is looked to the solution explorer window, *not the editing window*.

As long as the scroll bars are not present in the solution explorer, the scroll wheel works normally in the text editor window.  If, however, a path+filename, is long enough to cause the the horizontal scroll bar to appear, in the solution explorer, the scroll wheel is locked to horizontal scroll in the solution explorer.

If I open a file, in the solution explorer, that causes a tree expansion, and consequently the vertical scroll bar to appear in the solution explorer, the scroll wheel is locked to the vertical scroll in the solution explorer.

Is there any way to turn this 'feature' off?  I mean it is bad enough that the help feature in 2010 is a throwback to 1995, but who came up with this productivity neutron bomb?
