Is this a new problem? Were things working OK previously? Any new hardware and or software?
If this is a new problem try a System Restore to a point prior to the problem:
start > All Programs > Accessories > System Tools > System Restore
Here are some other ideas:
Right-clicking problems are usually caused because some program has
insinuated a hook into the context menu. Use ShellExView to determine
what third-party software has shell extensions. Disable all the
non-Microsoft extensions and see if that helps. Get ShellExView (free)

Right-click is slow or weird behavior caused by context menu handlers:
