ESC key behavior issue on Lordaeron

Hello,

I am experiencing a specific issue with the ESC key behavior on Lordaeron.

When I have a target selected and press ESC once, it:
- cancels cast (if casting)
- clears target
- immediately opens the game menu

All actions happen on a single key press.

On the same 3.3.5 client, when I log into other servers (including other realms), ESC behaves normally:
1st press – stop casting
2nd press – clear target
3rd press – open game menu

I have tested:
- 3 different clean clients
- no addons
- deleted WTF and Cache
- reset bindings

The issue only occurs on Lordaeron and seems account-related.

Could you please check if there is any server-side flag or account setting affecting ESC handling and reset it?

Thank you.

It's a problem with the anticheat. You have to install this addon https://github.com/Anyone0/EscFix
