hourglass cursor keeps appearing in my directx app!

Question

hi. i've created a directx game using directdraw and used the Cursor.Dispose() method to dispose of the cursor in the game previously. prior to doing this, the usual arrow cursor would appear during gameplay. this used to work, making the cursor disappear, but upon adding threads in the game, or perhaps due to other changes, the arrow cursor changed to an hourglass cursor and now refuses to disappear even after the usual Cursor.Dispose() method call. this is the only thing left to do before we submit our game for approval, so i'd really appreciate any help you guys can give. thank you. :)
