Are you stepping into the function or setting a breakpoint at a function?
You could be stuck in prologue or something.

To check if you are using a DLL with no debug info, you should open a
console window and type "info func TK_FUNC", where TK_FUNC is the name of
any Tk function in the dll. If it comes up as "non-debugging symbols",
you'll know that you've got no debugging on the DLL. You should also make
sure that Tk is compiled without -O2.

Otherwise, DLLs should just work. I've never had to do anything special
for them.
