Mouser: This may help some people.
I started this reply by explaining that I'm running Vista Home Premium, that Network adapter detection also failed for me, that device manager shows that I have an Intel PRO/100 VE, that clicking on Auto Determine Network Adapter didn't do anything, that you mentioned selecting "your card manually" however I couldn't because the drop-down list for Network Adapters was empty, blah, blah, blah......
...then before calling it quits and uninstalling the program, I read your suggestion to run url snooper with administrative rights... I right clicked on the icon, ticked run as administrator, restarted the program and voila ....IT WORKS.... it's showing the adapter as Intel PRO/100 VE and the program works as its supposed to.....
Apparently guys don't like getting or taking instructions.....had I tried running as administrator earlier I would have saved myself some grief.... btw, I thought I installed v2.18.01 but going to About shows that it's v2.17.01... did someone forget to change some text in the source code or does clicking on the download for v2.18 actually give you v2.17??
