EEventManager.APP always asks for permission to receive incoming connections
After upgrading to Mavericks on my iMac and my MacBookAir, my Epson BX525WD (PSC) didn't scan from the computers and it did also not scan to the computers over network by operting the scanner via its buttons. Most of the problems, that have been discussed here also, have been resolved with Epson support.
One issue is remaining: The Event Manager (EEventManager.APP), hat handles incoming communications if you operate the PSC from its keyboard, always asks for permission to receive incoming communication after you log into the computers. This is not only annoying but if you are not the admin, you also have to type in the admin's password in order to grant this permission. As an admin, I already changed the firewall setting to alllow this to EEventManager.APP, but this does not help.
Any suggestions?
iMac, OS X Mavericks (10.9.1), also MacBookAir w/ 10.9.1
