If you're using XP try this exactly:

1. Right-click the desktop.
2. Left-click the desktop.
3. Right-click any icon in the system tray (e.g. the time)
4. Right-click the desktop again.
5. Now try left-clicking on the desktop.

Why oh why does it do this!

If it does not work for you, give us details. e.g. what service pack you have, etc.

Anyone with Vista able to replicate this?

Spoiler:
To undo, right click then left click the desktop

I dont know what it's meant to do, but whatever it is, I'm doing it wrong.

Nothing happened for me

nothing happened

i failed to make anything bad happen

i think its a bug in your spyware

Yeah, it worked for me. Single clicking icons with the left button did what the right one would normally do.

Interesting!

Yeah it worked for me too.

for me it changes the left clicking to the same function as a right click... until you right click & left click again as per parabol's spoiler.

i dunno why it does it but i dunno why you are clicking like that anyways :p

Yeah on the 3 computers I've tried this on, the left mouse button started performing a right-click operation.

doesn't do anything for me, I was hoping for a foot massage or something

I assume that means that some people in this thread have a fix and some don't?

It doesn't do anything for me?

Yeah, did it here too. Does it happen on Vista?

Worked for me!

did it for me, annoying to say the least.

i also hate how sometimes the tray icon tooltips stay under the taskbar. Microsoft's solution? Reboot. http://support.microsoft.com/kb/912650

If it doesn't work for you, tell us what service pack you have or other details.

It's fixed in Vista! also, there are a few ways to fix it without rebooting. I used to just have tooltipfix.exe on the desktop and run & close it whenever I noticed I had that problem pop up.

and tooltip fix is here http://neosmart.net/dl.php?id=10

Edit: actually that's not the fixer I was thinking of, I was thinking of this one http://rapidshare.com/files/74854755/ToolTipFix.exe linked from this article http://www.raymond.cc/blog/archives/2007/12/08/fix-windows-tooltips-showing-behind-taskbar/

Edit2: OP's bug doesn't happen for me in Vista either (w/ SP1).

Yeah worked for me.

Has happened accidentally in the past too.

Also, I can do mine with 1 less step

1. Right-click the desktop.
2. Left-click the desktop.
3. Right-click any icon in the system tray (e.g. the time)
4. Right-click the desktop again.
5. Now try left-clicking on the desktop.

Strange, it was happening to me yesterday, but now it's not.

$ack's isn't working for me either.

XP, not sure what Serice pack .Work machine, aparently i'm not alowed to know that information WTF?

C:\Documents and Settings\sexgod>ver

Microsoft Windows XP [Version 5.1.2600]

doesn't do it for me - SP3

Cant Start>Run, Cant TaskManager>Rum. Cerainly cant get into CMD prompt.

I'm not really that computer techy though, so there probably is a way.

Hold the Windows key and press R, see if that opens the Run prompt.

Yeah puts the menu on the left button
