Well Challenge,
This is not AH related, really....but on my Mom's Win 7 64bit ult PC, when she plugs in her USB "Magic Jack" it freezes up what ever program she is in , or sometimes freezes up her Web Browser......
other times it is all ok....... then sometimes if after 5 or 6 calls come in.... it freezes thing s up again.....but soom as she unplugs the MagicJack, all goes back to normal... regardless if she unplugs all other USB devices..it is that one USB MagicJack device that causes problems.......
not sure if that helps any at all
