I had a very similar issue last Thursday with certain cards (using the
wpa_supplicant windows port), using Cisco 1100-series APs.  It seemed to
be timing-related (even clients that did finish the 4-way handshake were
having some minor issues).  After changing to version 0.4.5 (which
includes a change to the interval that wpa_supplicant checks for new
packets from winpcap while doing EAPOL), the issue went away.

Might be worth a shot, at least (but keep your old executables around
just in case).
