Description
I am using 1.5.7 on a dual boot Centos 6.5 And Windows 7 laptop. With Centos, the 4 arrow keys on the numeric pad do nothing when pressed in the IDE Editor. Same machine with Windows they work fine. The Page UP/DOWN and HOME/END work. Same keys work inside the Serial Monitor. Tried with builtin keypad as well as external usb keyboard. Same behavior on 2 Centos desktop machines.
Down graded to 1.0.5 and same results. This is the only application I use that exibits this behavior.
