I have installed the new AutoCAD 2011 on one of my companies machines. We have quite a few LISP routines that we have created buttons for on some custom toolbars. Now some of these are fine and some of the toolbars display blank buttons. The BMP files are all in the same directory. When I go to the CUI, and look at these toolbars, the icons are displayed on the toolbars there. Our 2010 machines use the same location for the buttons and they are now also displaying blank buttons on some toolbars. I'm baffled since the buttons display correctly in the CUI but not once I exit the CUI.
Any ideas?
