Gmail Lockdown
It looks like Gmail will lock your account if it is accessed at the same time from two different places. The problem is that I access Gmail from work and home, and as I reboot the computer at work only once a month at best and at home maybe ones a year, Gmail is always open.
But, the problem I feel is with Gmail itself. It automatically refreshes every two minutes. Users should atleast have the option to switch the two minute page refresh off.
The message that was displayed when the account was locked said upto 24 hours, but it was unlocked within a few minutes.
