Par locking, death, and purgatory

 I've had some strangness in my app for quite a while, the problem was
seemingly random, and the only way to fix was to reinstall, or install a
different version of my app.  I finaly figured out what is causing the
problem, and I fear it may be par related.

1. System reboots, or app hangs/gets killed.
2. App tries to start, looks for cache.
3. inc directory (win XP) is loocked, par freaks out loops forever.

What I need to do to fix it is to either change the binary (and cache
folder), or move the inc dir.  Windows woln't let me delete it because it is
locked.  Then the app starts up fine.

Any ideas why this is?  It is very difficult for me to simulate.  Any ideas
on debugging in a par built exe's early bootstrap stages?
