Samsung Galaxy Tablet

[fourteen85]

As you can see from an earlier post in Computers I am having problems with an ugrade to the firmware for my Samsung Galaxy Tab 10.1. Prior to the upgrade I used to be able to screen grab by pressing a button on the bottom task bar and the image would be saved in Gallery. That button has now gone and all I have now on the bottom task bar is a return button, a home button and one to access already open buttons. would like to still use this screen shot facility

Can anyone help with this please?
