the message box

[Jon]

I have been appending lines to a scrolling field to create a log file 
while running a program.  After a bit, I centralized the creation of 
these lines.  All of a sudden the Message Box started popping up.

I Filtered the Topics in the Documentation for Message Box, but nothing 
was there.  I Filtered on Message, and while something is there, there 
is nothing about the Message Box.

Any idea why the Message Box is suddenly getting triggered?  I must be 
doing something accidentally in this new regime.

Here is the current code:

on DisplayMessage msg
  put the long time & "  " & msg & Return after field "Memo"  
  set the vScroll of field "Memo" to the formattedHeight of field "Memo"
end DisplayMessage
