how can i make my whitebook not to go sleep when i close lid ?

hi, is there a way to set my whitebook not to go to sleep when i close the lid ?? i am downloading sth and i just want to go downstairs or move any moves with my mac..and once i close the lid it goes to sleep and connection is lost and downloading is disturbed. can i manage going to sleep manually ?

cheers

I second the suggestion for InsomniaX, it works great.

Click to expand...

it does not work great for me for some reasons..just keep quitting. and even if i manage to run it and then disable it i cannot enable it as it quits...when i try to restart it it dosnt work. i am using os x 10.5.2

are there any alternatives to insominax ??

cheers
