I have been using Quickbook Desktop with my MAC Computer for years with no problems.  I recently purchased a HP Computer and moved my Quickbooks to the HP.  My inventory parts transfered and I can used them with no problem BUT I can not add new inventory part #'s to my items.  When I enter the item it shows in the list but when you try to attach it to anything, Sales Receipt/Invoice or a bill it states that it is not in the item list and wants you to add it again.  Even if I add it again it still does not show.   PLEASE HELP!!
