+Bug#: 78725
+Product: Mono: Class Libraries

+TargetMilestone: ---
+Summary: System.Windows.Forms.KeyUp fires if you hold down a key.
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+Steps to reproduce the problem:
+1. Add a keyup handler to your winform.
+2. in the keyup event, put System.Console.WriteLine("Key Up");
+3. Build your project, hold down a key and observe output.
+Actual Results:
+Runs KeyUp event if the key never came back up.
+Expected Results:
+KeyUp shouldn't fire unless the key goes up.
+How often does this happen? 
+Additional Information:
+I've done this on Windows in .NET to handle input for games. I used keyup
+events to judge whether to accept input from a particular key. When keydown
+events were recieved a key was flagged to be used. The key's input couldn't
+be used until the KeyUp event for that key was fired. On Mono I can't do
+this, so I can't develop games the same way.
