I play on a Windows 10 box in windowed mode 1920 x 1080. About 25% percent of the time when I select offline mode in Trader, EQ hangs while switching from windowed mode to full screen. I am left with a completely black display. Then have to select CTRL-ALT-DEL, tab 8 times, enter, down, enter to shutdown the PC. Have to memorize the key sequence as the screen is all black with no way to recover that I know of. Wondering if this is a known issue? If you had this issue and resolved it what did you do? I suspect DB tech support would tell me to delete this and that file which hasn't done anything to resolve other intermittent issues (client hang on zoning from lobby to new instance of guild hall for example). So I prefer not to contact them and get a canned recommendation that will probably do nothing but waste my time.
