The easiest way to determine the version of VL that you are using is to open a terminal and type the following command:
Starting with the VL 5.8 series you should see the version name and number as well as the build date. When you are looking for help with a VL issue, it is a good idea to post the output of this command in your post. Better yet, include it in your signature (you can set that up through the Profile link). ;-) That way, the folks who help out will better know how to answer your question.
