Goach stunned us all the other day, by throwing light on a particularly dicey problem. IN CODE! (This was enumerated here.)
As a result, I looked through the stuff, had no clue how to correct the bug, and fell back on that time-tested adage: Google is your friend. This was followed by some laborious scouring of some rather tedious (and terse) JS references, and managed to churn out another version of the random number picker thingy. (Wow, used a lot of adjectives there, dinn'I?)
Hopefully, it works now..
