The inability to watch static variables in the VC6 debugger on WinXP/Vista/Win7 is a known bug with those IDE/OS combinations. Your only reliable solution is to run VC6 on Win2000 (or move to a newer IDE). There was a kludgy processor pack solution at one point, but that is not compatible with VC6 service pack 6. There are several free virtualization environments you can use to spin up an instance of Windows 2000 on your existing machine:
VMWare Player runs on XP/Vista/Win7 (note that you are able to create as well as run virtual machines with Player -- once upon a time you could only run machines created by other VMWare products. Note also that Player is free for personal or non-commercial use only.) http://www.vmware.com/products/player/faqs.html
