Sounds very much like an issue I have, but slightly different, where entering character select menu, logging in, changing channel, returning from rebirth, and opening options menu while fullscreen all causes the screen to turn grey and start blinking very slowly for what feels like 60 seconds before I'm finally allowed back in the game. This does not happen in windowed mode.

It happens to me as well. the most painful one is the one that occurs whenever I save in/open Options window.
It's very long, like 30~60 sec.
