Images above, moving my mouse over the area [near top of screen] there’s an unclickable field.

Sometimes it’s there, sometimes it’s not. Makes trying to mouseover / click on enemies within that field impossible.

Using /fstack there’s nothing in that area… what gives?

[Seriously stupid that I can’t embed images now that my Trust level’s gone down with the SL Beta “fix”…]
