[wp-poll] problem end-time

hello all,

I’m using wp-polls the last version i have the following problem:

when i’ve tries to planify a poll in future, i’m haven’t my poll displayed, for exemple:

when i’ve created the poll it was 23h30
start time 05/05/2011 at 23h40
endtime 05/05/2011 at 23h50

at 23h40 i’ve the poll after 2 minutes posted in my blog , and in my backoffice i’ve the status “open” instead of “future”, have the tag displayed with orange coloration.

it’s all ok at this level

now it’s 05h32 i’m waiting since 23h50 but my poll is yet active and i don’t have result off poll in place of this widget despite i’ve configurated it :

Configure it in Presentation -> Widgets -> Poll.
When Poll Is Closed:
Display poll’s results

Any idea??

thanks a lot

ps: sorry for my bad english
