Yep, bugs that don't show when you're debugging are always the toughest to exterminate.

You might try adding a wait window call with ALIAS() before and after your calls to cSelect:

WAIT WINDOW ALIAS() + ' is the alias before cSelect creation.'

CREATEOBJECT('cSelect', 'YourAliasName')

WAIT WINDOW ALIAS() + ' is the alias after cSelect creation.'

Since you won't have your debugger up, maybe it will trick the problem into rearing its ugly head just enough so you can start figuring out what's actually happening.
