Whenever I run Morrowind, it's running in windowed mode, and I can do nothing to force it to go full-screen. Can anyone tell me what might be causing this?

• In the options, it's down as being fullscreen.


• I am running no mods apart from Bethesda-issued expansions and plugins.


• I have run the 4GB patch and MCP


• I have told Morrowind to run as a High priority process through MWFPSOptimiser, but it runs windowed whether or not FPSO is running.

What am I missing?
