I'm using Windows 7 Enterprise. When I click on a favorite folder (left hand pane) in a My Computer window, it opens into a new window even though I have the folder options set to "open each folder in the same window". Is there anyway to change this?
Love it when people suggest conflicting things on forums... These things are all claimed to solve your problem!
The cause of this issue was that the explorer always gets launched with My Computer in the breadcrumb bar. This seems to break all kinds of things including opening each folder in it's own window by single clicking and breaking the breadcrumb bar itself, but the solution is simple (no registry edits required):
That makes explorer start in C: which avoids the whole problem.
