Switching accounts problems (during login) since feb 22 update

Since the feb 22 update i have problems when switching accounts...

I can login with 1st account just fine. But when i want to switch to another account, i get an extra window saying "connecting" and a cancel-button. I have to press the cancel-button to see my characters on that account.

I have this problem with and without the /newauth switch (i cant see any differences).

Ofcourse i can close the game and start it again, but that is an annoying option...

Are there more players with this problem?

Similarly, just about every time I change accounts, the entire application shuts down as I try to login to the next account. Everything just disappears, and I have to reload. That works, but "annoying" aptly describes that "solution." Likewise, this problem has only occurred after the 2/22 update, although unlike GODh, I don't even get the "connecting" window.
