I can also confirm this issue has happened to me on multiple Distro's, this is all running on my CR48 Chromebook from Google (beta test), using a Synaptics touchapd.
LUbuntu 12.04 Fedora 13 (LXDE) Linux Mint 14 Debian 7.2 and many others I have tried. I never knew of any of the fixes listed above until just now, and the switching to a VT and back to X worked for me.

I'm talking about the touchpad and not the external mouse. The first thought would be to check whether we have given the option to lock the touchpad while typing. But, my pointer (touchpad) gets stuck simply often. The slightest of deductions I have been able to make is that this happens sometimes just after using the touchpad scrolling.
