[opensuse] wpa_supplicant config/cache changes prevent connection w/o wpa_cli/wpa_gui?

Here is a new one for me. After using madwifi/wpa_supplicant on Atheros hardware from 2004 on, yesterday I was stuck unable to connect to my wireless AP a work. In the past, all that was ever required to connect with wpa-personal/psk(tkip) was to create a network block for the wireless AP you wanted to connect to using:
# wpa_passphrase <ssid> [passphrase]
Then all that was needed was to include that network block in /etc/wpa_supplicant/wpa_supplicant.conf. On wireless start, the network blocks are tried in the order they appear in the .conf file until a connection is made (or you can set priority within each block). Despite having done this countless times, yesterday it simply would not work.
I saved the original wpa_supplicant.conf -> wpa_supplicant.conf.sav and created a new one that contained only the network block for the AP I wanted to connect to & restarted networking (full rcnetwork stop; rcnetwork start). Despite only having 1 network block in wpa_supplicant.conf, the socket '/var/run/wpa_supplicant-ath0.conf' still contained the network block for my home AP. Huh? So I stopped networking again and confirmed that wpa_supplicant-ath0.conf was deleted when the network shut down ... and it was.
After 20 or so minutes of frustration, I looked at wpa_cli and wpa_gui. Both allowed you to set the wireless network connection information, but I had never used either in the seven years before. Firing up wpa_gui, I was able to 'add' a network for the office AP and viola, I got a connection. The frustrating part was I could NOT save the network configuration despite having 'update_config=1' in wpa_supplicant.conf.
Long story short, does anybody know why wpa_supplicant appears to be ignoring the network blocks in wpa_supplicant.conf? Also, why does the socket '/var/run/wpa_supplicant-ath0.conf' continue to be created with my home AP information -- even when I am connected to the AP at work? And... why does it look like either wpa_cli or wpa_gui are now required to change wireless networks when simply conf file changes were all that were required in the past?
Any ideas would be appreciated.
