Hello, I just upgraded to DOSBox 0.72 a few days ago and have been having lots of fun with the new speed enhancements! Anyway, just a few minutes ago, for whatever reason, DOSBox has decided to stop working, and crashes on startup with the following message, "Failed to create hardware surface."

Here's the detailed diagnostics:

* Motherboard: MSI P965 Platnium
* Processor type and speed: C2D E6400 (2.13GHz)
* Amount and type of RAM: 1GB DDR2 800
* Video board w/ RAM amount and type: eVGA GTX 8800 (765MB)
* Sound board: Emu 1820m
* Operating system: Windows XP Pro w/ SP2
* Game name: N/A
* Description of problem:

Error message shown when trying to start DOSBox 0.72:

Failed to create hardware surface.

Then crash to desktop.

* Reproducibility of problem: always
* Sound mode used: sb16
* Video mode: 1280x1024x32
* Version of emulator: 0.72
* Steps already attempted:

- Rebooted
- Stopped ZoneAlarm
- Ran Windows Update, installed about 30 updates, some notable ones:
* Network card driver update
* .NET Framework 3.0
* Root certificates update
* Windows Genuine Advantage Validation tool
- Also earlier today I installed the latest version of Google Earth.
- I have read the readme, unfortunately nothing that I could find to match my problem

Like I had said, the odd thing about this is that it has been working perfectly up until now.

Many thanks for any help. 😀
