Well it hasn't stopped working completly, but it stopped working in finder, as in : you cannot size icons/thumbnails anymore. Let me start from the top. Me and my girlfriend both have early '08 MBPs, both were running 10.5.5 and it was all good. Then my GF upgraded to 10.5.6, and her touchpad stopped responding to gestures in finder. I guess it has something to do with four finger gestures they were suppose to support now, replacing touchpad driver with the late '08 one, but that didn't seem to work either. Because she works with image thumbnails a lot, we decided to downgrade to 10.5.5 (I tried copying pref pane and various files from my machine but I failed), and it was ok for a while, and she decided not to upgrade anything until they fix it, so she wasn't upgrading (at least that's what she said) and multi touch scaling stopped working again. You can still do it if you press cmd+j in finder window, but it's quite annoying. We were hoping to find some information about it somewhere on the net but either this problem has not been widely recognized or I didn't search for long enough, anyway I decided to post here to ask if any of you have similar problems. The easiest way to check that is to click on the desktop and perform a scaling two-finger gestures - drive icons on the desktop should scale nicely. Does it work on your machine? Which version of OS are you running? Does anyone know anything about that broken driver?
