Frustration with template debugging

Question

Using:
Sun Studio IDE 7.4 2005/10/13
Sun Dbx Debugger 7.5 Patch 121023-01 2006/02/09
CC: Sun C++ 5.8 Patch 121017-02 2006/04/19
Problem:
Using Studio 11 debugger GUI, file in which template is defined is not opened when I step into a function belonging to the template.
For example, when I compile the test files below with "CC -g -o testMe testMe.cc", then attempt to step into the t.set(5), testMe.hh is not opened.
However, if I manually open the file, set a breakpoint in it, have the breakpoint triggered, then remove the breakpoint, I can step into the file from then on, even across sunstudio/dbx restarts.
Does anyone else have this problem?
Test files:
testMe.hh:
template <class Type>
class T
public:
        void set(const Type & copyMe) { myT = copyMe; }
        Type myT;
testMe.cc:
#include "testMe.hh"
int main(void)
        T<int> t;
        t.set(5);
        return 0;
}

Sun Studio IDE relies on a file extension to determine file's type and it doesn't open files as directed by the debugger if it doesn't know this file type.
Unfortunately, this is not user-configurable in current release, but fortunately .hh was added to recognizable extensions list and this fix is available in the following patches:
- 122142-01 for sparc
- 122143-01 for x86
