Can't write configure.php

[dtakle]

When I right-click on a .php file, the context menu shows:
Open; Scan with AVG; Open in Notepad++; Open With ...;
Send To >>; Cut; Copy; Create Shortcut; Delete; Rename; Properties.
Clicking on Properties gives a dialog with only one tab: "General"
There are also check boxes for "Read-Only" "Hidden" and "Archive"

Win2K ... when you right-click on the file, what options do you have ?
Further, if you right-click and choose Properties, what options are you left with, and what tabs across the top?
