"Press any key" lag issue

I haven’t been able to find any previous post for this same problem, so here goes. I keep having an odd lag issue where I’ll perform an action - say moving something from bank to inventory, or interacting with an NPC, or even casting a spell in combat - and the action won’t complete, it will just hang indefinitely, until I make a keystroke. It’s almost like any action I perform is a “press any key to continue” kind of thing. And it does this with add-ons enabled or disabled, it doesn’t matter. Can anyone tell me what’s happening here? Thanks!

Hi,
Try Repair your disk in recovery mode
if that does not work, reset your UI

Google on how to do the above as I can not send links.

Cheers

VERY reminiscent of an issue I was having (the Movement Bug? thread). After much discussion Omegal pointed me in the right direction. Pressing a key results in 2 actions, a KeyUp and a KeyDown event. Sometimes, that KeyDown event can be interfered with. Sometimes it simply may not register… possibly due to lag.
