Changing Topic Mid-Thread

[JonnyMac]

Please help us keep these forums useful for all: keep your threads on one topic.  If you start a thread on topic X and then attempt to change it to topic Y we will simply ignore the new question until it it posted in its own thread.  Yes, we know this is a minor inconvenience, but must insist if these forums are to remain useful. 

Thanks for your help and understanding.
