Hi, I'm using the GIT HEAD of Emacs' Cocoa port on MacOSX 10.5.8 PPC and GIT HEAD of AutoComplete . The problem I'm having is that the point in the Cocoa port doesn't return immediately after typing and a post-command-hook has fired off a function to be run with an idle timer. Supposedly AutoComplete should be a whole lot faster with the new timer-based completion trigger in HEAD, but this bug in the Cocoa port seems to be preventing that. I've tested this with Emacs 22.3 in the terminal and CarbonEmacs 22.3 and both has the cursor return immediately. I'm guessing something in the NS code that deals with the point render is waiting on the idle timer thread instead of having both threads running asynchronously? Jimmy Yuen Ho Wong
