Re: Application starts too soon

Evidently I will need to do something similiar. What I don't get is why is
there not a method in XPE to wait to run an application until the OS is
fully loaded and the command shell is up and running? I've searched around
Windows XPE site and looked thru the two XPE books and found nothing on this
topic. It seems like once they walk you thru the getting a shell up, they
figure the job is done. Oh oh, I'm starting to rant.....

I've got several third party add-ons in my software, it may be difficult to
tell which is hanging up, how it's hanging up, and what do do to fix it.
