New to forum.

I'm a brand new user of LibeCAD and have come to this point because of costs.  I was a user of Turbo CAD and Auto Cad for 13 years but my limited use makes it extremely difficult to justify in budgeting.  I really like using LibeCAD but I have an issue. I've searched the net and can't get a fix for the problem.  I am not able to bring up the command bar by tabbing [Widgets - Dock widgets - Command line ].  This effort brings up the error message [File '' does not exist. Opening aborted]. Has anyone else seen this error message? What would be a way to trouble shoot this error? Is it going to be necessary to reinstall? Thanks to all who will read this.

You could try Application Preferences -> Defaults -> Clear Settings -> Layout

You could use the Dock Areas toolbar to hide/show the command-line.
You can also undock the command-line and use the "Floating" button (Dock Areas toolbar).
