For any one else who clicks this forum query.
The problem I had was the right click in explorer 32bit would show the menu but nothing within the menu would respond. It works a treat in explorer 64bit and in the Inprivate browsing both 32 and 64 bit.
I am using Win7 64 Ultimate.
Now the way I fixed mine after several days browsing forums was simple. So simple I was tempted to throw the whole sytem out the window out of spite.
1, Open the offending explorer.
Click on the Tools tab. (If it's not shown press Alt first)
Select Internet Options.
Select the advanced tab on the Internet Options new window.
At the bottom of the window click on the Reset button in the Reset internet explorer settings.
I then checked the Delete personal settings box. (Don't know if it would make any difference. But it does also delete all cookies and a lot more).
press the reset button.
It will then result in a new window, Reset Internet Explorer Settings with a green tick next to 4 sections. Press on the Close button.
a final window will appear saying For changes to take effect, you will need to restart Internet Explorer.
Press OK. Then Close your Explorer Window.
Open your 32bit Explorer and now it should work perfectly.
It was possibly maleware or some kind of virus. It may even be an eccellerator so watch what you reactivate or install.
Happy Browsing All
