Hi.
I've got a problem.
All the games I run in DOSBox flip out whenever I go fullscreen. Everything works fine in a window when I start it up but as soon as I hit Alt+Enter the game and the sound starts lagging like crazy and the graphics starts to flash like it's shifting between 16 colors and 16 bits. If I hit Alt+Enter again it goes back into windowed mode and works just fine again. I simply can't figure out why it's doing this. In Lotus 3 it only goes crazy in fullscreen at startup and in the menus. During actual gameplay it works fine in fullscreen.
This is driving me insane! 😠
Can anyone help?

I'm using the latest 0.73 version of DOSBox on a brand new Windows 7 64 bit computer.
