That fix isn't a true fix, it just changed the window name so the game cannot find it, and the command you're putting in the eq2.ini is doing absolutely nothing.
A real fix would be to hide the window the first time it comes up with an OnShow event and only have it fire off once.
Add a property to the first <Page>:
HiddenOnce="false"
Add the OnShow property, also to the first <Page>:
OnShow="visible=HiddenOnce
HiddenOnce=true"
Note: I didn't test this. but it should work
