Windows XP has two options for "opening" a folder: "Open" and "Explore". Ordinarily, double-clicking a desktop folder (such as my computer) will use the "open" command, while either "open" or "explore" can be accessed via the right-click menu. Then, if it is opened using "explore", double-clicking any folder within will open in the same window with the same settings (regarding "folder" view on left hand side).
In the aim of making the initial double-click use the "explore" command, I used "folder settings (file types tab)" to set the default action as "explore". This worked, however if a folder is being viewed without the "folder view" (i.e. having used the "open" command), a new window will be opened using the "explore" command. (The same thing but in reverse happens if I set "open" as default). This I do NOT want. I want the same window always used.
What I would like is to have the initial soft selection of command returned, rather than the hard selection I have currently. I can't return to the initial "no default" setting as the "folder options (file types tab)" has only a "set default" option, (no "remove default" option).
System restore did not rectify this.
I am comfortable using regedit if two or more people suggest the same thing and nobody disagrees (or you convince me I should).
(Sorry, I've removed some of the niceness in asking the question to try to be clear. I will be grateful, despite my tone. Thankyou!)
