Problem with building standalone

[larry at significantplanet.org]

Approximately 20-40% of the time when I go to build a standalone, the LC IDE just quits - without building.  I have to restart LC and try again.  Usually, this is what happens:  I again ask to build the standalone.  LC asks if I want to save my stack, even though I had just saved it before attempting to build the standalone.  If I say "don't save" then LC usually just quits again.  If I save it again, then LC usually (but not always) will go ahead and build the standalone.

I'm using Community 6.1.1 (rc 4) on XP Service Pack 3

Thanks for any advice!
