Re-Login failing?

[Wickerman]

I'm baffled by this one.  I have a few logins set up with different privilege sets attached.  I have a button on my main layout with the one-step "Re-Login [with dialogue:On]" script step attached.  Next to the button I have a little merge field displaying the name of the current Log-in account.

Logging in either way at the beginning is working fine, as expected.  When I try the Re-Login button and enter a different account, the merge field displays the change appropriately . . . but the privileges aren't changing over accordingly!?   This happens in either direction -- whichever account I start with, those privileges remain in force. (One of the accounts is all-access, the other has a very limited Privileges Set).

I can't fathom what's amiss here -- any suggestions?

I figured out the glitch  - silly little thing.  So this topic can go away
