using vBKM under Windows XP Pro, as soon as I tell BKM to export to a Firefox file, vBKM just quits (looks like a crash, no message at all). vBKM does not create even a 0-byte output file. I have Firefox 3.06 installed (but since the export is to a file, not sure what difference that makes).
I had told ZoneAlarm firewall to block communication from vBKM out to Yahoo - don't know if that would make any difference, but did not know vBKM would need to communicate to Yahoo.
