[DUG] 'Stupid' Dll question

[Robert martin]

Hi

This might be a stupid question but....  If I create a dll do I have to
do anything in relation to multi threading?

I have a Dll that has two calls, each call creates and object
(referenced in a local variable), performs some processing then frees
the object and returns a result.

How does windows handle multiple apps / threads calling a dll?  Is it
one virtual instance of the dll per thread or some other scenario?

I know lost of questions but I just want to get it straight in my head.
We think this dll may be crashing and wonder if it is to do with being
called by two threads simultaneously.
