Backburner In maxscript - Need Advices

Hello there, I'm again looking for your help, i just finished the first version of my second script, and hope i can post it here in the future for all of you.

But first i've got a litle problem, with backburner. I'm Trying to use function to get control of the queue to submit a large amount of files. In fact, i have another option to use a batch with vray spawner, wich work perfectly but in case i want backburner to deal with it, i need it to work properly.

The problem is the control of the queue, i don't want to get it by force, and i want to promp the current queue controller and take it only of he / she let met (in fact probably "He")

Here's a quick view of my current code.

I choose to open each file and send it to backburner, to keep the current setting of the scene. but the script crash sometimes if i didn't get control,I think it's because of the #wait option but i need advice(s), i hope you guys can tell me more about backbuner in maxscript, cause i don't get it.

Thank's in advance for your help.

Big up to barigazy, if you read this, you supported me last time i needed help here, and i can't stop Max-scripting since then :)
