JoinBattleFiled() blocked

[fgprodigal]

I'm writing my own UI now. I find that if we do the following thing step by step:
1. Toggle the MiniMapTrackingDropDown by ToggleDropDownMenu(1, nil, MiniMapTrackingDropDown, "cursor")
2. Open LFDFrame using ToggleLFDParentFrame()
3. Click the PVP tab
4. Click JoinBattleField button.

Boom, it is blocked. But if we open the PVPFrame by hotkey, it is okay.
So, does any author know how to fix this. This also happens when no addon is loaded.

PS: Sorry for my English.

Protected functions need a hardware event.

Some protected functions need a hardware event, many more can only be run by secure code. There's no way around this and even if someone found a way, Blizzard will block it.

You typed in that script into the chat box? That's essentially the same as an addon doing it, for the record. But yes, there are a number of issues with dropdown menus tainting stuff, namely the PvP UI.

Many UI kill the minimap tracking button, they toggle the minimap tracking dropdown menu by right click the minimap instead (by ToggleDropDownMenu(1, nil, MiniMapTrackingDropDown, "cursor")).
Some UI (like ElvUI) can toggle PVE frame by middle clicking the minimap (by ToggleLFDParentFrame()).
So the problem is:
If we toggle minimap tracking dropdown first, then we toggle PVE frame and switch to PVP tab, we can never join the battlefield before reloading ui.

Yes, just type it in chatbox. JoinBattleField() will be tainted.
