darkvater 44c39c5ebc (svn r1547) -Feature: windows dedicated (if anyone would run that, but ok), is now functioning correctly. There is no other way but to create a new thread, but that's only MS braindeadness 
-Fix: [1103113] font size changing. Dedicated server did not have code filtering, 'tab' could result in bigger fonts
-Fix: [1103069] console backspace key with ded server; fixed due to normal console handling
-Fix: [1101963] console in dedicated server; see above
-Fix: dedicated server also writes to log file if active
