Let me follow up on Matt's question. I have an application (Keyspan Digital Media Remote) that sends keystrokes to other applications. It uses CGPostKeyboardEvent for this. The OS X and Classic environments respond differently when there's a delay between key-down and key-up actions. If I do this

CGPostKeyboardEvent(charCode, keyCode, keyDown=1);
// some time elapses
CGPostKeyboardEvent(charCode, keyCode, keyDown=0);

and an OS X application is in the foreground, it receives a single key down, followed up a key up later. A Classic application in the foreground receives a key down, some number of key repeats, and a key up.

Is this a bug? Ideally, I'd like both OSX and Classic apps to work the way OSX apps do, but if there's some architectural reason that doesn't make sense, then I'd like some way of figuring out whether to issue the key up immediately (so as to make the Classic apps work right).

You may have good reasons why you prefer the OS X way, but to me the classic way seems to make a lot of sense. If I physically hold down a key for a while I get key repeats until I release the key again. Why should this be different for CG remote key events? Is it perhaps also a difference depending on whether carbon events of WNE is used?
