Whenever I press the left shift key, the right click menu pops up.

This is similar to the problem that I found discussed here: Shift key pops up a menu

I ran a keyboard test, and it shows that whenever I press the left shift key, it registers that as shift + the menu key, which also brings up the menu (see screenshot below).

enter image description here

I know shift + F10 does this, and I am fairly certain the F10 key is not stuck.

Has anyone ever encountered this problem before or can only suggest some methods to solve this?

Does this issue only happen with this one keyboard? – Dave Jan 7 '13 at 8:31
Yes, it seems that this is keyboard specific. What I don't understand is why or how a single key is registered/mapped to two keys. This also seems to happen with the LWin and LAlt keys, and pressing either ends up registering as both keys pressed. – Kevin Jan 7 '13 at 8:35
Well, the keyboard is faulty! Or, you have some software/driver specific to the keyboard which is creating this 'shortcut' or 'autohotkey' type of thing! – Dave Jan 7 '13 at 8:36
Although it's most likely a hardware fault, can you check if it does the same in Safe Mode as well? – Karan Jan 7 '13 at 21:26

As this issue only happens with the one keyboard, then it may be worth while just getting a new keyboard to save any headaches.

You can down load the free tool AutoHotKey and map the Shift + Menu combination to just the left shift and see if this overwrites the fault.

Obviously this will only work if you never need to use the combination Shift+Menu

John, I think my answer is an OK answer, but, I suggest you wait a few days and don't mark it as answer to see if any one else posts! – Dave Jan 7 '13 at 8:48
@John, I have updated my answer with another option. – Dave Jan 7 '13 at 8:55
I have decided to return the keyboard. I was able to re-map some of the keys, but I'd rather just have a fully functional keyboard. – Kevin Jan 13 '13 at 7:34
