Hi , can't change my full screen view to Window Mode when pressed ALT+ENTER. It just popped out a black box with numbers. Manually also doesn't work. Again , it pops out a black box with numbers in it.
Hello! Can I please have a screen shot of the error you are getting? It would help me further diagnose your problem! Edit: If you cannot get a screen shot than can I know a better description of the error other than it's a black screen with numbers.. like what number are you getting? Because it may be that your monitor does not support the resolution.
Does it make a Windows 'error' like sound? What fixed it for me was setting my monitor refresh rate to 60Hz, some monitors have default 59Hz and somehow Maplestory Window mode does not like that. Rightclick desktop, go into screen settings, into advanced settings, and pick the bottom option, something like change monitor adapter settings, on the tab Monitor, there should be a drop down menu where you can select 60Hz as an option!
