I have a form to re-index a table If I use the code

IF USED('users')
	USE IN users
ENDIF

USE users IN 0 EXCLUSIVE
SELECT users

I get the error message

File in Use

In the debugger used('user') is .F.. Why does VFP 9 think the file is in use? If I use the code

USE users IN 0 EXCLUSIVE AGAIN 
SELECT users

or

USE users IN 0 EXCLUSIVE AGAIN ALIAS users
SELECT users

I do not get the above error message, but in the code

lnNoTags	= TAGCOUNT('users')

DIMENSION alcTagInfor[lnNoTags,6]

=ATAGINFO(alcTagInfor,'users')

FOR lnCnt = 1 TO lnNoTags
	lcTagNane		= ALLTRIM(alcTagInfor[lnCnt,1])
	lcTagExpression	= ALLTRIM(alcTagInfor[lnCnt,3])
	lcTagOrder 		= ALLTRIM(alcTagInfor[lnCnt,5])
	DELETE TAG &lcTagNane 
	INDEX ON &lcTagExpression TAG &lcTagNane &lcTagOrder 
NEXT

I get the error message

File must be open exclusively

on the "Delete Tag ..." line.

What file is VFP 9 looking at?

Why am I getting these error messages and how do I fix this problem (using Stonefield STD is not an option)?
