Thanks Jeff for clarifying the part on MemHandleFree(). Thanks to that I have been able to focus on the memory leaks: in my attempt to resolve the MemHandle-problem (or at least I thought it was a problem) I forgot to free a couple of pointers. So in effect your answer allowed to focus on the only real problem, the leaks, and it's all been taken care of now :)

There was a brief discussion in this forum about that a couple of weeks ago; it turns out MemPtrUnlock() is a little faster than MemHandleUnlock(), so that's why I use that form. It's not quite intuitive, but since it's more efficient I've gotten myself used to it. Thanks again, your reply made all the difference!
