I haven't been able to nail down what causes this to occur but whether I'm only logged into a single account or 3 accounts the game will just close. No error windows ever pop up. I'm not able to reproduce it at will. I'm running Windows 10 64-bit
Make sure you have Alt-Enter unchecked.
Already done :) still happens though :'(
The best I can think of is to make sure sciw.exe and wlaunch.exe are running as admin with XP SP2 compatibility mode.
If you can come up with firm reproduction steps it will help a lot :)
I produced it, but not anything I did before. To see if I could get it to stop I unchecked tabbed mode and tried with separate windows. Within moments of doing this on 2 instances of realm both closed almost simultaneously.
Also, I just checked what you suggested and they both are running as admin with win10 sp2.
I think I figured out when it triggers. @Gimli as I stated previously, I run it as admin and win xp sp2. When I started a battle is when it happens 9 time out of 10. For whatever reason, started after I ran windows game mode alongside Realm.
