Sqlforms 3 , oracle error ORA-01001 - invalid cursor

        Working environment:

		SUN:               SUN OS v4.1 
		Oracle:		   v6.0.33.1.1
		PL/SQL:  	   v1.0.32.3.1
		SQL*FORMS(runform) v3.0.16.7.1

	I have a peculiar error when I execute a certain FORM that CALLs
	another one. the error is 'ORA-1001 Invalid Cursor'.  This error
	appears either in the first form or in the CALLed form.  It is 
	very erratic in nature, but eventually, I always get the error.
	All the SELECTs were converted into CURSORs, but that didn't change
	anything. Sometimes, I get the error 'ORA-1475 must reparse cursor
	to change bind variable datatype' instead of 'ORA-1001'.  Would it
	have something to do with memory allocation and/or management ??
	Any help would be greatly appreciated.


	Thank You
