The OpenEdge Debugger preferences are categorized into two: General and Communication. You can optionally use these preferences to manage your Debugger environment better.
General preferences
Enable property evaluation: This preference gives you the option to choose whether you want the evaluation of properties with accessors to automatically occur. The preference is disabled by default. If you enable this preference, you see the actual value of the property in the Variables view. (A property added to the Expressions view is always evaluated, whether or not you select this preference.)
Always select first matching file upon CRC mismatch: This preference allows you to choose whether to always select the first matching file and ignore the rest, if there are one or more files with a similar name but none of them match with the Cyclic Redundancy Check (CRC) of the program being debugged.
Communication preference
Connection timeout: This value indicates how long, in milliseconds, Progress Developer Studio for OpenEdge waits to connect to the OpenEdge Client. The value is set by default to 20000, but you can modify it to your preference, provided the value is no less than zero and no greater than 3600000 (one hour).
