Double click on trackpad not working.

i have the exact smae problem, it started when i updated my software and my magic mouse stopped doing the double clicking too. Please advise

okay so i fixed my trackpad!!! what i did was update my software to the latest version 10.6.4 and i went to my settings and clicked trackpad and there was the double click speed option and i put it into the middle and it started working, double click selects text and plays music in itunes now! hope this works for you!

I'm having the same issue with the double-clicking except I tried what Zac suggested and my double-click speed was already on fast. Anyone have any other ideas?

mine was on fast but i moved the slider to about the middle (between fast and slow) and it started to work again. Try that.

Thanks Zach, my double-clicks stopped working, with BOTH my new magic trackpad and my mouse. It was the setting in Trackpad Preferences, as you pointed out, and when I returned it to the middle, my clicks were clicking again. Amen.

Well, yes - for a while.

But my experience is that the midrange double-click setting that I set doesn't last. Some time later, it moves to the "fast" end and I have the same problem and have to do it all over again. Why?

That has not happened to me (above). My preference setting for double-click speed stayed in place. It should not change.

So why? -- Perhaps a conflict with something else and I think of my use of BTT (the freebie preference software I've previously mentioned). It also has speed and sensitivity setting. -- so I had to set my settings in both these preference.

Maybe worthwhile messing around with BTT, since it does also has seed and sensitivity settings for the trackpad, even if you're not interested in it's other features.

!? - I don't know or have any connection with BTT, by the way; but it's free so I tried it. There are also OTHER people who make software to help control the trackpad (jltouch - http://www.jitouch.com/index.php?page=jitouch ) -- is $6 but they indicated they were working on a new version update to now include this new Magic Trackpad, so I didn't try them.

But_ Preferences are not suppose to 'just change,' for no reason at all. The 'old computer trick,' comes to mind: delete the preference pane and download the software again and reinstall.

i have the same problem with my powerbook running 10.5 and my macbook pro running 10.6. is this all from updating?
