CAPTCHA, Round 1.3

I have installed and subsequently removed the previous 2 versions of Miguel Jimenez’s Clearscreen
SharpHIP HIP-CAPTCHA Control.  Not that Miguel is churning out a bad control,
to the contrary, he is doing the rest of us an invaluable service.

Version 1.3 of his CAPTCHA solution does not
address the issue that caused me to remove it the first 2 times, but due to excessive
spamming, I must go ahead and keep the CAPTCHA solution in place.

The problem that I am having is that if a user forgets to enter the code, or gets
the code wrong, the text of their comment is not retained in the post-back and the
comment that they typed is gone.  I know that I have lost at least one comment
from someone who alerted me to this behavior in the first place.

My implementation for now provides the following test below Miguel’s CAPTCHA control:

Note: If you get the above code wrong, or forget to enter the code,
you will lose the text of your comment.

I have to admit, this solution is far easier and less desirable than taking the
initiative to actually get into the code
myself.  I am sure there is a way to deal with this issue, but I suspect that
it involves modifying code.
