Don't think it's a resource problem at all since it's a brand new system, it does seem to have alot of restrictions on site pop-ups and what not. Rebooting doesn't help.
So far it's been only one this one particular site (my blog site). I do notice that the drop-down menus appear for like a fraction of a second then disappear, if that gives any clue.
edit: It seems this problem is just occurring on a single webpage, so I'll just contact those in charge. Thx.
