Right click not working Windows 7 x64

[nietzsche]

Hi all,

I would really appreciate some advice/help! Last night, while playing a game, the right-click function stopped working on my mouse.

I left the game and returned to my desktop, where the right-click also proved to not work anymore. I restarted, installed updates etc. - nothing.

I have lost all functionality. I have left quick only and even my computer seems to be running poorly (at times). I didn't do anything out of the ordinary, this seems to have just randomly happened, and I can't figure out why. It's quite dehabilitating and I don't seem to be able to find any solution (after searching/googling).

I'm fairly certain it's not the hardware, although I haven't tried a new mouse. This is a brand new HP computer running Windows 7; if someone would provide some feedback that would be great!

Thanks a lot!

Let's try restoring the computer to a date prior to the mouse failure.

Also wouldn't hurt to run virus scan and malware bytes, as you claim other issues.

Try Karlsnooks approach first.

nietzsche,

Welcome to the existentialist SevenForums.

Do you have an extra mouse that you can try? Sure sounds like a mouse problem.

Hi! N, welcome to W7F

Three things come to mind

• If it is a wireless mouse the batteries may be strong enough to show the light, but not send the signal.
• The right click micro-switch is bad.
• A problem with the (CMH) Context menu handler registry key.

• HKEY_CLASSES_ROOT \ Directory \ Background \ shellex \ ContextMenuHandlers

• Some times third-party applications will add a key there.
• Sub-keys to it are okay, but the CMH, and any sub-keys should only have one entry, the default value.
• If you find any additional entries in the Context menu handler registry key, create a sub-key to the Context menu handler registry key, and then remove what you found.
• Be sure to create a reg-backup!

Thanks for the replies all. I'm going to try your suggestions.

Cheers!

Let us know what you find out!

Prost!

Hi all,

So, I did a system restore and it came back with an error saying that it didn't work (even though I noticed things had returned to how they were on the 18th). So, thinking I had created an even bigger problem I decided to undo the system restore...and everything is back to normal; the right-click works.

I really don't know if this is going to be a permanent fix, but thanks again for putting me on the right right track. I feel slightly dumb for not thinking of this first, but what can I say, I'm more of a Mac user.

Cheers all!

Good. And even Mac users are welcome here!

That is good news for now, but as you have mentioned earlier you noticed poor performance, and a poorly coded context menu handler (shell extension handler) may be the cause.

There are different areas; file class, folder, allfilesystemobjects, HKCR\* registry keys where these extensions are added, and it becomes a process of elimination to find what extension can be the culprit.

This can help:
ShellExView - Shell Extension Manager For Windows

I downloaded shellexview...

Question, if the problem comes back, would I just deactivate the shells and then check the mouse to see which shell is affecting it? - moreover, would I do this for all of them until I found the shell that was causing the problem -is it just trial and error?

Thanks!

Well you wouldn't want to disable them all at once or you could run into bigger problems.

Did you read "Disable and enable the shell extensions" part?
You can narrow it down if you disable according to their type, and it will go quicker.

There is more on this page, including a tip on how to troubleshoot by disabling half at a time.
