Toshiba's PR firm just hit us up to say that they've tackled the oversleeping problem the Thrive tablet has been experiencing, and a fix is on the way. To wit:
Toshiba recently became aware that a limited number of Thrive Tablet users were experiencing Resume issues when in Sleep mode. We have heard from a Toshiba source that a software update to resolve this issue will be available early next week and can be accessed from the Service Station utility app found on the Thrive at that time. This will improve sleep-and-resume performance, as well as enhance the multimedia playback capabilities of the device.'
Not a bad turnaround for a fix -- in and out in just a few weeks. Shame it had to happen in the first place, but these things do happen.
