I am on a library computer, windows 7 and codeblocks has frozen, for well over hour and I can't cloe it. I was in the middle of compiling a program after correcting an error in syntax and taskmanager won't let me close it either. Either when I choose end task or end process nothing happens.
That sounds odd. Maybe Windows 7 has an incompetent task manager? Maybe some other part of Windows 7 crashed? When in doubt, restart the system (if the library permits it).
