Clicking Menu > Logout does not bring up the Logout/Shutdown/Restart menu anymore but causes the screen to go black. How can I fix this? Thank you.

Perhaps it's a temporary glitch.  Can you open a terminal and type in sudo reboot?  If you can reboot this way and the logout options begin to work again, I would suggest you open Systemback and create a restore point for the future.

I was able to reboot from terminal as you suggested. I will try the Logout button again to see if the shutdown/restart dialog comes up and let you know. Not sure how to open Systemback to create a restore point though.

I tried clicking the Menu > Logout button again and got the same result, the screen goes black. Any other ideas? Thanks.

Consider the following few options:
    1) Do a web search on the words "xfce logout button goes black"
    2) Look into this link.
    3) Look into this link.

Thank you torreydale and firenice03. I tried the suggestions at the links you both provided and couldn't fix the problem. So, torreydale, i used the workaround from one of your links (https://bbs.archlinux.org/viewtopic.php?id=159958) and am using a custom launcher on the panel that works like a charm. Thanks again to both of you.
