If you have a resolved or unresolved problem with the software, please submit a problem report. This helps bugs to get addressed and the feedback improves the documentation and user interface.
Suggestions are also welcome and are often used.
Thanks for your feedback. Check the software's Problem Reports web page. If your problem is listed you may still wish to submit a problem report if you believe you can provide additional information on an unresolved problem. Read and search the documentation. The idea is to provide enough details for the problem to be reproduced, or else tracked down in the source.
