There is a remaining issue -- which was there before but which I had not posted about. If I Suspend/Resume, then on resumption the driver disables the Aero theme and points its finger at XWin.exe as the culprit, saying it did something incompatible with Aero. You probably know about this stuff, but here's the overall blurb anyway: ----------------------------------------- Why are some visual elements being automatically turned off? If you receive a message that some visual elements, such as window frame transparency, have been turned off, or if you receive a message that the theme has been changed to Basic theme, one of the following might have happened: A program that you're running is incompatible with Aero themes. When this happens, some visual elements are automatically turned off. When the program is no longer running, the visual elements that were turned off are turned on again automatically. Your laptop might be running low on battery power. Windows might turn off Aero themes or window transparency to save battery power. Your computer's hardware configuration or screen resolution was changed. If you changed your screen resolution, video card, or monitor setup, your computer might no longer meet the minimum recommendations for running Aero themes. Your computer does not have enough memory to run all of the programs that you have open and also run an Aero theme. If Windows automatically changed your theme to Basic theme, and you want to change it back to an Aero theme, close some windows to free up memory, and then follow the steps below. To run the Aero troubleshooter To try to get visual elements like transparency running again, use the Aero troubleshooter, which can find and fix problems automatically. Click to open the Aero troubleshooter.‌ If you are prompted for an administrator password or confirmation, type the password or provide confirmation. To use an Aero theme If the troubleshooter doesn't fix the problem, try changing the theme back to an Aero theme. Click to open Personalization. Under Aero Themes, click a theme to apply it to your desktop. ------------------------------------------------------------ As soon as I exit XWin, Aero reasserts and remains if I restart XWin. This is a minor annoyance compared to SIGSEGV. Recently it has happened on *every* Resume; in the past it seemed to me that it happened only *sometimes*, with a pattern I did not figure out. So this is perhaps of lower priority, but would be nice if it were fixed at some point. Thanks again for your quick response!
