Setting the number of months to display to 0 or blank displays no months.

The module in the block section when setting up the number of months to displays says to either enter 0 or leave it blank if you want all of your months it creates to be displayed. However, it is outputting no months at all.

I'm using Drupal 5.1 on a XAMPP 1.6a installation on Windows 2000. I haven't tried it on my server yet, just the test bed on my computer. (I like to make sure I'm not going to have problems with a module before throwing it on a live site.)
