Got my calculator yesterday and was playing around with it today generally following examples in the user manual. After a while I noticed that the calculator switches off and restarts when I click the Advanced Graphing App Icon. Tried a reset by "on" and "symb" with no result. Also tried to reset using the pin hole at the back. Still the same result when clicking the Advanced Graphing App icon. All other icons work fine (or at least does not restart the calculator).
I then connected the calculator to my computer using the Connectivity kit. Whilst the calculator shows up in the Connectivity Kit window, when I proceed to click on the arrow expanding the calculator contents, the calculator restarts. Downloaded the latest firmware and updated the calculator, all to no avail. The behaviour is exactly the same.
Settings; Standard Number format, Textbook Entry, Decimal Integers, Radians. Changing these around has had no effect.
Any suggestions for what to do next? Is there a setting I may have inadvertently changed etc..?
By the way should the clock be reset if a new firmware is installed, as I notice that it has remained correct throughout.
Thanks for any help.
