Hi, I'll be happy to help with this issue
can you check this option?
Apple Menu-->System Preferences -> General
and make sure that Restore windows when quitting and reopening apps is unticked
let me know if that resolves the issue
if not, can you let me know what version of OSX you have installed?
the problem is that I usually WANT the files to reopen, but only the ones open when I quit. It was adding several from previous sessions/restarts
Apologies, the messages on the 11th didn't notify me that you had responded and I will be offline shortly so I will open this to other experts in the meantime
They should send you a message when they are available
