Problem cancelling form in init

I have run into a problem that I have never encountered before. Typically, if I want to cancel the instantiation of a form for whatever reason (based on conditions), I check for a condition in the form's init method, then if it fails, clear events (if it is a single form app) and return .f.. However, for some reason in my current small single form app, when I cancel events and return .f., the form closes, but I am returned to the vfp screen with no form. If I turn on the debugger, I am sitting at the read events command just below where I called my form, even if I issued a clear events before the return .f. in the form. Any ideas? I must have overlooked something here somehow.

Code in main.prg calling form:

*--Run Main Form
DO FORM Rebuildall WITH llautorun, llforcedbf, llforceindex, llresult, llpolcall
READ EVENTS
IF llresult
*--Return to calling program ok
RETURN .T.
ELSE
*--Return to calling program with an error
RETURN .F.
ENDIF

*--Code in form's init method
*--Create the archive directory
IF !DIRECTORY(thisform.bakdir)
MKDIR (thisform.bakdir)
ENDIF
*--Verify its creation
IF !DIRECTORY(thisform.bakdir)
CLEAR EVENTS
llresult=.f.
RETURN llresult
ENDIF


Thanks for your help!
