I did, and verified that it removed the comment.  I didn't notice that it
also eviscerated the function!  A trivial fix avoids that problem:

on mouseUp
  put removeBlockComments(the script of me)
end mouseUp

/* this is a comment
as is this */function removeBlockComments pText
put pText into tText
put offset("/" & "*",tText) into tOffset
if tOffset > 0 then
  delete char tOffset to tOffset + offset("*" & "/",tText,tOffset) + 1 \
      of tText
  put removeBlockComments(tText) into tText
end if
return tText
end removeBlockComments

Since I don't recognize that need, would you elaborate on it, please?

Thanks for catching my oversight, Alex.
