Every now and then the member lists will not pop up when writing code.  It
just makes it alot easier.  Anyone know if I could be turning this off by
accident?

Thanks
Tom

Sometimes the Intellisense won't recognize the function that you're calling,
so it won't flash up the member lists.  Specifically this will happen if
you're calling a member function of a class that's not defined in your project
or it's a non-MFC derived class (third party tools, etc.)
