Hey...
I'm having the same issue.
Tried the advice...cleared cookies,
then switched to board tine - which worked, altho' of course in a different time zone from me...
then switched to user time zone - and it went blank again.
Using FF 1.5.0.3 on win98. Incidently, getting same error msgs in javascript console as bob gray.
Tho' i can use the board's time zone...it is a small inconvenience
one gets used to little comforts.
