I'm running XP SP3 on a Thinkpad T61 with an Intel Mobile 965 chipset.

My about:support doesn't give me any details about my hardware, just "Direct2D Enabled: false DirectWrite Enabled: false GPU Accelerated Windows: 1/3 Direct3D 9".  

However I can get info from Grafx Bot's Welcome page when I click the "System Info" link on the page - " Display Vendor: Mobile (0x8086), Display Adapter: Mobile Intel(R) 965 Express Chipset Family, Display Chipset: 0x2A02, Display RAM: 384 MB, Display Drivers: igxprd32, Driver Version: 6.14.10.5218, 1-13-2010, Display Settings: 1440 x 900 x 16"

I wanted to see how dynamic Grafx Bot "System Info" link was to changes in the runtime environment, so I decided to play with the bpp setting.   The Display Settings line didn't change.

Reproducible: Always

Steps to Reproduce:
1.Install trunk with Grafx Bot 0.1.23
2.Set Windows Screen bpp to 16
3.Run Grafx Bot and click System Info
4.Observe Display Settings line.
5.Change Windows Screen bpp to 32.
6.Open a new Minefield window (bpp switch with XP causes Layers screen corruption, but will go back to normal on window reload, so I figured this was fair)
7.Re-open Grafx Bot in new window
8.Observe Display Settings line.
Actual Results:  
Display Settings stayed at 1440 x 900 x 16

Expected Results:  
Should have changed to 1440 x 900 x 32.

Exiting and reloading Minefield does then let Grafx Bot report the correct colour depth.

Going from 32 -> 16 also fails.

Thanks Barry.  It's true that GrafxBot runs it's hardware detection at startup only.  That should be fixed.

If you want to generalize this even further, what would happen if there was a screen res or bpp change during a test run?  Is there a check for a consistent runtime environment in the test run?
