Hi there,

It seems that irb has problems with the arrow keys on Windows. Steps to
reproduce:

1. Start up CMD.
2. Type "irb" and press return
3. Type "abc" and *do not* press return
4. Press the right arrow key
5. Now try typing "defg" - the characters don't show up anymore. If you
press return followed by the up arrow key, the whole sequence you typed,
including the mysteriously invisible characters, shows up.

I'm using ruby 1.9.2p0 (2010-08-18) [i386-mingw32] on Windows Vista
32-bit, installed by extracting the 7z archive provided by the
RubyInstaller team to C:\Rubies\ruby-1.9.2-p0-i386-mingw32. Of course I
added the bin\ subdirectory to my PATH variable.
I don't know wheather in matters, but I don't have the RubyInstaller's
devkit installed, but a separate MinGW+MSYS installation in C:\MinGW
which is up-to-date.

Anyone experiencing the same problem?

Valete,
Marvin
