4. Problems on Specific Hardware and Operating Systems (i.a. Windows and Macintosh)

4.1: Some keys (arrow keys, ^) do not work on Windows.

What happens is that the Windows keyboard driver (or the keyboard scan routine in the CYGWIN library we use to build the Windows binary) do not send proper keycodes to GAP. (This can depend on the version of Windows you are using.)

It also depends on whether you are using a non-english keyboard driver. (For example the keyboard drivers for some non-English languages catch the '^' character to produce the French circumflex accent. Switching off the French keyboard driver will resolve the problem.)

We unfortunately do not have enough Windows expertise to remedy this. (One can type POW(a,b) for a^b.)
