Carl,
We don't currently have capability to mark an open issue as resolved or enter what the resolution was, although this is something that has been asked for so hopefully it will be available in a future release. In the meantime, you can use a convention to mark an issue as resolved, e.g. as you mention, add something to the resolved column, or add a prefix to the open issue text, such as RES: for resolved. You would have to embed the resolution of the open issue within the open issue text, or you could use the ResolveBy column for this purpose too.
You can report open issues using existing Word reports or HTML reports that come with CaseComplete. However if you want to report only the resolved open issues, you could customize the OpenIssues word report to add a where clause, for example:
$tableOpenIssues where Description StartsWith RES:
or
$tableOpenIssues where ResolveBy <> ''
Hope this answers your questions, but let me know if not.
