Patrick,
Jim's solution is probably better.
I find it frustrating when I am apparently given the choice of all these
options, but for some unknown reason cannot choose them.
Why give the user all the days of the month if only a single day is valid ?

Another approach would be to use a list box with only the last
Thursday of each month listed.

I asked this question a couple of days ago and got a response (but the
response while it would work, did not fit into how I wanted to set up my
form) so I thought I would try one more time:

Is there any way to lock a Calendar control in such a way that someone
could
only select a Thursday? Ideally the last Thursday of the month.
