Occasionally, I encounter a computer glitch or crash which causes JAWS to stop speaking. When this happens and there's no sighted assistance available, I just shut down my computer using the power button on the tower and reboot, which usually restores JAWS to normal speech. I've heard that shutting down a computer this way is not a good idea since it could cause hardware damage, so is there a better way to get JAWS to start speaking again without sighted help? Thanks.?
