pretty hard word;
I understand however that you definitely want this working.
The reason, there was no answer is probably:
It is obviously something ``deep down in the bowels of the C code'' for

and "usually", these things are left to R&R for fixing.
On the other hand, Ross and Robert are always overloaded with work...

If you feel knowledgable to do it in C, we'll be more than glad for your
contribution... !
