I am using the beta 4 32 bit dvd. This did not happen in prior betas. During install partitioning, I elected to customize my own mount points. On the screen that allows you to select the option of mounting or not, when I select mount and then type a mount point nothing appears where I typed. The mount point is taken when you complete the screen but you cannot verify it is correct until you leave the screen and look at the summary. Obviously this is bad since you cannot verify as you type the mount point.
