If you look at this bug thread the same issue I was seeing was found to be a coding issue
Blank reply screen Were also with mine it was also quick reply with same blank screen so as Rick stated there was a short timeframe where some of us downloaded V7.5.6 that had the issue and then a newer build was done with the fix included.
People should test both quick and full reply posting to assure they do not have the problems
As to file rights it could be so that a host tech caused that though if the coding had not been a issue a tech would have never been screwing around looking for a fix.
