Strange and irritating recurring matter on my SB2 15". Periodically, and at random intervals, when I get to the logon screen, when I am in reverse screen attached mode (tablet turned around with the keyboard facing backwards) when I am at the logon screen, the virtual keyboard that should pop up when I need tap the screen to enter my password won't come up. I have to either a. Hit the Settings button, bottom right of the screen, each time and select the On Screen Keyboard which is a full keyboard. b. Detach the screen, touch the password entry field which then pulls up the correct virtual keyboard automatically, re-attach the screen and then logon Anyone else seen this type of issue or a resolution..?
