This is a variation on a theme I have seen in several places, but still different.
Preface: I usually have only 3-6 icons on my desktop, and I hardly ever use them; otherwise I might have noticed more immediately.
Sometime in the last 2-4 weeks, it has come to be that:
(a) There are not icons visible on the desktop.
(b) When I right-click on the desktop to get the menu about organizing icons and changing the display, nothing at all happens.
(c) If I try to drag an icon from the task bar or the START menu to the desktop, the cursor displays as the circle-and-slash "cannot do this" icon, and it appears that nothing happens. But see note (3) below.
(1) This only happens in my account on this machine; the other 3 users' desktops work just fine.
(2) Context menus in Windows Explorer and in all other apps look and behave just fine.
(3) If I make the "Desktop" toolbar visible in the Taskbar, the icons are all there after all, including ones I recently dragged (but *apparently* failed) to the desktop.
I have downloaded and used ShellExView, but could not find anthing amiss.
One person suggested it was a problem with:
HKEY_CLASSES_ROOT \ Directory \ Background \ shellex \ ContextMenuHandlers
However, I checked that, and the only entry besides "New" was the one for "InCDMenu", which I've been using for months and months.
This is WinXP Pro w/ SP2, which has been running successfully on an Intel P2 or P3 for over a year.
Only thing that's really new is the monitor.
Need further information?
Any ideas, recommendations, etc?
