My guess is that it's a driver problem even if you're using a newer one than the one HP has listed. Have you tried rolling back to the one on HP's site? It could also be a problem with the power management settings. Some kind of conflict when the machine wakes up that takes some time to resolve, but again, could be a driver problem in that it's not managing the wake up process properly.

This is a model HP custom made for Best Buy. Running Wndows Home Premium 64. I have a very strange problem with the touchpad. When I close the clamshell and put it to sleep, it ofter wakes up in a state where the touchpad does bizarre things. It won't select applications on the task bar. When IE goes to Work Offline mode, the dialog box that pops up won't select -- exactly 3 times. On the 3rd try it always selects and then IE goes back online. The driver on my computer is newer than the driver HP offers online -- scary. I have found that if I use Task Manager to kill and restart explorer.exe the problem goes away. I'm not able to find any information online about this problem. Any searches I do for ALPS are complicated by a certain mountain range. This is pretty low-volume computer and this is a very obscure problem so I know this is a long shot, but if anyone has any theories I'd be curious. /rich
