when Rev fails to send mouseEnter

[Dick Kriesel]

Here's a recipe to demonstrate that Rev usually fails to send mouseEnter to
a nearly vertical line:

Create a new mainstack.
Paste the following four lines into the multiple lines message box.
  create graphic
  set the style of it to "line"
  set the points of it to 200,100&cr&208,300
  set the script of it to "on mouseEnter"&cr&"beep"&cr&"end mouseEnter"
Press enter.
Move the mouse across the line at various points along the line.
Notice how rare the beeps are.

If you change the width of the graphic, the failure rate changes:  the
steeper the line, the greater the failure rate.  If you choose the pointer
tool, you can select the graphic where the beep occurs but can't select it
where the beep does not occur.  The problem does not affect a vertical line.

So a bug report seems worthwhile.  Does someone have insight into what the
problem actually is, or related evidence?

I've tried this only in Rev 2.7 with OS X 10.4.5.
