You have connected to a pcAnywhere host, but at some point, the remote window stops responding and the connection is lost.
There can be conflicts between video card drivers and pcAnywhere. A newer driver will usually solve the problem.
This problem is usually caused by a video driver conflict at the host. To resolve the problem, uninstall pcAnywhere from the host machine, download and install the latest video drivers for your video card, then reinstall pcAnywhere.
