802.11 Decryption works under Mac, doesnt work under Vista

Hello,

I'm capturing traffic from my home Wi-Fi network using MacBook Intel laptop
in promiscuous mode (802.11).
I setup 802.11 decryption in Wireshark for MacOS using known SSID and
passphrase. Decryption works, I'm able to see tcp packets in the packet
flow, the IP's and contents are real.

The problem appears when I try to open saved pcap files under Windows Vista
at another laptop. I can't decrypt neither using passphrase+SSID, nor by
generating PSK key sequence using online tool
http://www.wireshark.org/tools/wpa-psk.html.

My home network encryption settings are Security type: WPA2-Personal,
encryption type AES (this is what I observe in "Manage Wireless Networks").
The wireshark is the latest downloaded from website.

br,
Ivan
