IOS 4.1 / iPod Touch 4th generation and Wiindows 7 Ad Hoc Networking issue

I have an iPod Touch 1st Gen that I have been successfully using with my Win2k, Win XP, and Windows 7 laptops to transfer files via Windows' Ad Hoc Networking for a couple of years.
I just received my new iPod Touch 4th Gen iOS4.1 a few days ago and have been having trouble connecting to my Windows 7 laptop using Ad Hoc networking. On Windows 7, I created an unencrypted ad hoc wireless connection. When I try to connect with my Touch 4th Gen, the network status on the laptop keeps on saying "Waiting for users". However, if I try with my Touch 1st Gen, the network status immediately says "Connected"
Touch 4th Gen connects properly to ad hoc networking only to my Win XP and Win2k laptop. When I connect via a wireless router / access point, the iPod Touch 4th Gen is able to ping my Windows 7 laptop and I am able to do FTP file transfers. VPN PPTP and IPSEC connectivity works fine.
So the issue seems to be isolated to iOS4.1 / Touch 4th Gen and Windows 7 Ad Hoc networking.
Just tried my Touch 1st Gen iOS 3.1.3 and it's able to establish Ad Hoc networking to all windows platform that I have.
Anyone else seeing the ad hoc networking with Windows 7 and iPod Touch 4th Gen issue?

I have iPhone 4 running IOS 4.1 and ThinkPad running Vista and am experiencing a similar problem. I am able to connect to the ad-hoc network (using WEP encription as WPA2 didn't work at all) however I cannot get internet access through this network connection. My wife has an iPhone 3GS running IOS 4.0.2 and she has no problems at all connecting to the ad-hoc network and getting a connection to the internet.
I also find that my phone does not remember the pass code to connect to the network and I need to enter it each time I try to connect. The option to "Auto-Join" the network always slides back to "OFF" when I exit from the network setup page. Again my wifes phone does not have this same problem.
Looks to me like it is either an IOS 4.1 issue or iPod/iPhone 4 hardware problem.
