I have now repeated this with on 2 different routers runningispyisail: I'm having trouble reproducing this browser bug. I've tried firefox 13 in Windows XP with 1.5.6 and it seems to work fine.. any more details you could provide to pin down the bug would be helfpul.
1.5.6 and 1.5.x (1.5.5+)
Both client machine need to be running Windows XP SP2 and firefox 14.0.1
I've also seen this fault on a window 7 machine but never vista
Where do want to go from here?
teamviewer, VPN into the router, SSH or all of the above?
