I tested the 32-bit installation DVD. During installation, I can move the frame of the installer (the right part of the screen), from partitioning screen until the end of the installation screen. Otherwise, when I tried to install Grub2 (I installed the system on a usb key with a single root partition, and placing grub2 in the mbr) but the system refused (too little space to install grub2). So I installed Grub1 (graphical mode) in the MBR of the usb key, and that's ok. On some choices (during installation), I must click twice for activate the choice.
Otherwise, I have not encountered others problems that these ones during the installation.

Bye.
