<p>The background color of all the toolbar icons in my PMail (4.63 build 325) has turned black for some reason. It's not an issue with respect to the function of the program itself but the graphics on some of the icons is difficult to read above the black. I've looked through the configuration settings and don't find anything that would affect the background color(s).  Sometimes when/if I reboot the machine the backgrounds will come back white but eventually turn to black again. Kinda wierd ... anyone else experience  this? Is there something I'm missing in the configuration?</p><p>Thanks ...</p><p> </p>
