I'm sure many of you are familiar with the INPUTHISTORYMODE system variable, first introduced AutoCAD 2006. This sysvar controls the content and location of the display of a history of your command input and allows you to decide if your command input history gets displayed and where (command line, tooltip, context menu). It doesn't affect the display of commands that you entered, it affects the display of input values that you provided to commands, e.g., points that you picked during a LINE command.
If you're one of those people that sets INPUTHISTORYMODE to 0 because you don't like AutoCAD offering you a history of recent input values, you will have a problem recording macros with the Action Recorder. If INPUTHISTORYMODE is not set to at least 1, the Action Recorder will not properly record input. It seems to record some input from using the Properties Palette but it doesn't play back reliably.
At present, the only workaround for this is to set INPUTHISTORYMODE to an acceptable positive value prior to recording an Action Macro. The INPUTHISTORYMODE setting does not affect playback of Action Macros - only recording.
