I've made a total mess of my setup, what files can I delete to reset it?
 The MrDebug files
──────────────────────────────────────────────────────────────────────────────

 If the problem is related to horrific colours on the screen, then simply
 delete the colour file that is causing the problem. To find out which colour
 scheme is causing the problem, press <Shift><Alt><.> followed by
 <Shift><Alt><,> and make a note of the number of the last colour set
 reported on the screen. Use this number to delete the colour scheme file.

 For example if the message from MrDebug is:

        Switch to colour set 4
        Switch to colour set 3

 Then you want to delete the file called COLORS3.MRD from the directory
 pointed at by the MRD environment variable.

 If the problem is not colour related, but something to do with your settings
 then you need to delete one of MrDebug's settings' files.

 The first file, of which there is one for each application that uses
 MrDebug, is created in the directory pointed at by the MRD_LOCAL environment
 variable. If this is not set, then it will be created in the directory that
 the application was run from.

 The file is called the same name as your application and the extension is
 .MRD. You should first delete this file if you are having problems and then
 run the application again to see if the problems persist.

 If you are still having problems, then it is time to delete the GLOBAL.MRD
 file. This is used by MrDebug to store all of the settings that are common
 to each of your programs that use MrDebug.

 This file can be found in the directory pointed at by the environment
 variable MRD. If there is no MRD environment variable, then this file will
 be created in the current directory

 This should cure all problems. Although you will have to replace all of the
 settings that you have lost from deleting these files.
