Hello guys, I have this problem:
I double click wow.exe to enter the game, it loads but it stays in bar.
I try to click on it on the task bar, i hear the login sound for a second and it gets back in the bar.
i tryed to use "maximize" or "bring to front" but it doesn't work.
In task manager, wow seems to be running in memory, (no HDD disk comsumption).
This occured after my win10 updated.

can u please help me with some info? I looked around but I didn't find anything useful. Thank you very much,
