This is very strange as I certainly only posted it once. It appears to be some type of resubmission error but surely your forum software should be capable of eliminating such duplicate entries be they system or user initiated?

Not sure what you mean by "multiple topic postings" I came to your support site after a google search did not reveal any quick solution was there any other user having same issue? The catgeory chosen seemed the most appropriate to my issue.
