I've just upgraded from ACAD2000 to 2010 almost seamlessly. My 2000 has a lot of customised lisp routines and 95% work fine so far. What I have notice though is that the menu buttons say for the standard "draw" menu has only question marks instead of descriptive icons. Any ideas?
As a possibly related issue, when I open my old ACAD2000 I find my home made menu doesn't appear, although it does on 2010, and the standard menu buttons are boxes with blacked out centres, no icons, not even question marks which are probably a 2010 feature. Zoggie.
