R help - Feb 2016 - readline is not working

HI,
I am new to R and English is not my natural language.

I work on 4 laptops that are supposed to be the same. Win7-64. R version 3.1.0.
I can use readline to enter a value from keyboard on three of them but not on
the fourth : R doesn't stop on the readline instruction and acts as if the
response was 'enter' and I think that the cursor 'disappears' .

What can I look for ? environment variable, GUI preferences, ... ?

Thanks in advance for your answers ...
Jean in France

Hi Jean,
Many laptops perform complicated workarounds to accommodate the virtual
keypads on the keyboard. Sometimes a sticky shift key (e.g. NumLock, Caps
Lock) will mess up keyboard entry if it is on. Just a wild guess.
