VB6 RIGHT CLICK NO LONGER APPEARS IN CODE EDITOR

I recently have come across the issue in which the right click functionality no longer works in the code editor of vb6 enterprise edition. If I right click on controls or other menu items, the menus appear, but if I right click to copy code or bring up the context menus, nothing appears. Any suggestions? I am running Windows XP SP3 and VB6 with SP6.

Thanks,
