Ok I have sorted this issue by forcing dosbox into full screen mode, even though never had to do this on the p30lite but who knows?? Thanks anyway

Hi, I have been using freebox on a Huawei p30 lite running championship. Manager 97/98 with no issues. I have installed both on a Huawei p30 pro and if you rotate the screen to landscape it reboots dosbox. Any help would be appreciated Cheers Chris
