Hi,

I have installed DOSBox on my PC and set it up to start with a full screen and it worked fine yesterday when I installed it, but now I get this error. If I do not use full screen in settings, then I can start it up.

Eroor:

CONFIG:Loading primary settings from config file C:\Users\Palle\DOXPortal\DOSBoxPortable\Data\settings\DOSBox.conf
MIDI:Opened device:win32
Exit to error: Could not set fullscreen video mode 640x400-32: DirectDrawSurface3::Lock: Invalid parameters
