Hi all, I'm having a bit of a quirky problem. This happens on OSX, but might happen on windows as well. I've found an SDL situation that causes the mouse to forget or mess up its state via a series of right/left clicks. While the OS maintains the correct state, SDL starts reporting mousedowns as mouseups and vice versa. What I wanted to know is, is there any way to reset the state of the mouse? I'd like to go ahead and just reset the mouse's state whenever the app reactivates and not even worry about this. Thanks, John

You can duplicate it like so:

Make a simple SDL app. Just have it display mouseup/mousedown and your mouse motion. I can only vouch for OSX, not Windows.

Now:
1) Left click and hold on the app screen
2) Drag the cursor off screen over the desktop
3) Right click on the desktop (left click should still be held down)
4) Right click on game screen and hold (left click is STILL down)
5) Release left click and left click the game screen (Right click is STILL down)
6) Release right click.

Now, if you watch your messages, you'll see that you only get mousemotion events when you're dragging-- i.e. the left button has to be down. Otherwise, no mouse motion events. Very screwy.

Nothing strange happened here. I got all motion events and all button events as I'd expect.

It may be something OS related, so you may wanna try posting in the SDL mailing list.
