Enable property evaluation - Check this option if you want the evaluation of properties with accessors to occur. This option is not enabled by default. If you do not select this option, you see Property evaluation disabled in the Variables view as the property value, instead of the actual value of the property. (A property added to the Expressions view is always evaluated, whether or not you select this option.)

Always select first matching file upon CRC mismatch - Select this option if you want to always select the first matching file and ignore the rest, if there are one or more files with similar name but none of them match with the CRC of the program being debugged.

Connection timeout (ms) - Provide the time-out value that you want the Progress Developer Studio for OpenEdge Debugger to use when connecting to an OpenEdge client. This option is enabled with a default value of 20000 milliseconds.
