Triggering an alarm on MBP while the lid is closed I would like to use an alarm clock application on my MacBook Pro. The thing is, that I need to close the lid on the MBP while sleeping. Now I know this is a common issue, but after moderate amount of Googling I haven't found any reasonable solution. Some solutions are already old, do not work on 10.6.7 or the current line of MBP.

This application almost works. It has everything alarm clock should have. It can wakes the computer from sleep as well. It has some problems with closed lid though. The alarm fires of, but after like 3 seconds it auto snoozes. After snooze cool down expires the same thing happens again. If the lid is open and MBP is sleeping the application works just fine. 

Can anyone recommend any other application? 

ps. Now I know, that running MBP closed is not recommended due to possible overheating, but all need it the alarm clock, so after 10-20 seconds I will manually turn it off, so it shouldn't be an issue.
I used to use InsomniaX, but it has stopped working with the recent updates, and the developer's site says he's stop development. However, I found a similar app that works called InsomniaT. It's not quite as useful as InsomniaX, but it gets the job done.
