We're using Sage 100 2015 Standard, and we're attempting to upgrade from Windows 7 and Office 2010 to Windows 10 (version 1803 specifically) and Office 2016 but testing is revealing an issue in which if Sage 100 has been left open and inactive for a period of time, the next time we try to open a task (any task at all) we get the following error message:

Input/output error

Program: SY_SESSION.PVC

Statement: 6950

Class: SY_Session

Method: SetLastActivityTime

Sage 100 then will not respond and we have to end the process using the Task Manager. The knowledge base gave me the idea that it might be a printer port issue, and indeed I found that a new Office 2016 printer, "Send To OneNote 16", shares the "nul:" port with the Sage 100 PDF Converter printer. Therefore I changed the port for the Sage 100 PDF Converter printer to a different one (I made a new Local port named Sage), but unfortunately this actually had no effect on the problem, so that's not it. Anyone else experiencing this issue by any chance?
