The brief answer is Excel.
All things have their limits; just make your title and message more
succinct.

I am finding that the length of message I can put in the "Title" and "Input
Message" fields in the Data Validation dialog box is too small. In the
Title
field, I can barely fill half of the line before the input keys stop
working.
And in the Input Message field, where it looks as if I could put 7 lines,
I
can barely get four lines.

What is limiting the input? How can I extend the input?

Thanks.

Mike
