Thief 3 Deadly Shadows - Vanishing Mouse Cursor

[Thunderduck]

I am running Thief 3 Deadly Shadows on a brand new Dell desktop.

When I run the game, at the main menu screen, the mouse icon is frozen. You can select the menus by moving the mouse, but the cursor is basically invisible.

I've updated my onboard graphics driver, installed the 1.1 patch, tried running in Windows XP Compatibility mode, it still wont work.

Although this computer doesn't have a commercial graphics card, I have run numerous modern 3-D type games with the onboard graphics, including intensive games like Elder Scrolls IV Oblivion which require tons
of 3-D rendering.

Here are my specs:

Windows 7 Home Premium Service Pack 1
Dell Inspiron 620
Intel Core TM i5 2320 CPU @ 3.00 Ghz
64 bit
6 GB RAM
Intel R HD Graphics
