Blue screen in test game

[j1mm3h]

after creating a background importing it into ags and setting where to walk and boundaries i chose to test the game (this is using the "default game" template) the game starts up and the screen is a solid block of blue after moving the mouse around it appears to rub out the blue where ever the cursor travels or the character travels. any suggestions as to why this is happening?

I had this happen just now by accident when i imported a 16 bit background in i had forgot to change the colour depth to 16 bit so it was on the default 256 colours.
I got a message saying that the image was 16 bit and my game was 256 colours and that the room would be unusable. I tested it and and i got the blue screen. i then went back and changed the colour depth to 16bit and it was fine.
