Exiting to a prompt and restarting X reverts the display back the initial desktop size specified in xorg.conf (I'm using Xorg 7.6 to use the xf86 vmware driver and vmmouse), so I'm basically starting over. Right clicking on the bar does move it to the bottom, but it is then on a black background and the rollover graphics don't work as expected. Also, the right click trick is only useful when making the screen larger. If you make it smaller, then it's hidden and you can't right click on it to reposition it. I have it set to top left for now so it's not that I can't use it, I'm just thinking "now that I have my homemade vmware client tools extension working, it sure would be nice if wbar stayed in the bottom middle of the screen". So, yes, this is a low priority "option for auto reload on resolution change" enhancement request.
