My tooltip popups disappeared

[CoolBuys1290]

When I mouse over an icon in Window selector and when I mouse over an item that's in the loot bag, the tooltip words don't show up. Please help. Thank you.

Reboot your computer

Is there no other way? I have a lot of programs open.

Tool-tip/mouseover text disappearing is a known issue if playing on some Windows systems after about 27 days without rebooting the computer. I've experienced it myself. Sad to say, the only known way to correct it is a system restart.
