Explorer 7, 8 Right Click not working problem Solved
Recently I had an issue with Explorer, the recent ms explorers both had right clicking issues where you cannot right click at all; the right click would work in all the other programs including Firefox. To solve the problem I had to go in the registry and edit the values below.
1) Go into regedit
2) Go to: HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Restrictions
Look for “NoBrowserContextMenu” – on mine there was a value of “1″
I changed it to “0″, closed explorer and tried it and it worked.
This seems to be an explorer bug. The ms techs solutions doesn’t work, they say remove any addon, un-install super-antispyware or that it could be a virus. The above instructions work for me, hope it does for you, leave a comment if it works. Thanks.
This issue made sure I stop using Explorer, switching full-time to Firefox. Two Thumbs up to FireFox always, explorer (lowercase) is a designer’s nightmare.
