Game keep switching to full screen and windowed alone

[Baler]

Make sure your game window size is the same as your full screen size and both match your display resolution. In your eqclient.ini file under [VideoMode]

That is if you want to play in fullscreen...

edit: also verify the boolean for WindowedMode=FALSE
And if you want to play windowed, make sure your Windowed resolutions are set proper in the ini and windowedmode=true

Please let me know if either of these were helpful or not, for future troubleshooting.
