Until recently, I have been running AutoCAD 2009, but upgraded to 2010 earlier this month. Probably since AutoCAD 2002, I have used a Lisp program called by keystrokes defined in a "acad.pgp" file, to pull down certain customized menus from the menu bar. At startup the custom menu files are loaded and the Lisp routine is used to pull down or "Pop" (display) the menu. The problem I am experiencing is that the Lisp program no longer pulls down any menu. The menus are succesfully loaded as can be seen by the title on the menu bar and also, they can be manually pulled down by selecting the title.
In short, the Lisp code to pull down the menu, (menucmd "p13=*"), no longer functions after installing AutoCAD 2010. However, I still have AutoCAD 2009 installed on the same computer and it works well. Both versions of AutoCAD use the exact same customization files: Acaddoc.lsp, ".mnl", and ".lsp", etc. files. Also, the new compiled menu files, (AutoCAD 2010: .cuix - AutoCAD 2009: .cui, mnr, etc.) are created from the same original ".mnu" file.
I have tried simply entering the (menucmd "pn=*") at the command prompt, with no success, except when I use n=0, in the Lisp command. Only then, a context menu appears, which is not a pull-down. No other menu slot number works. However, all slot numbers (1-16) work as expected when I launch AutoCAD 2009.
I am aware AutoCAD has changed the compiled menu format AGAIN!!!!!!! in 2010 and I wonder if something is not working correctly in this new format, or if there is a new system variable that I am not aware of, that freezes the menus. (Can't imagine why.) The circumstances seem to point to a "bug" in the new menu structure.
Any help would be appreciated.
