[Mono-winforms-list] NumericUpDown test case (with the right file attached)

[jba-mono at optusnet.com.au]

Appologies, I sent the wrong file last time (please ignore the last email with the MonthCalendar.cs attached)

Hey guys.

Attached is the simplest NumericUpDown Value bug testcase I can come up with.
Clicking on the test button changes the value from the minimum (1953) to 2004. Running this test case on windows (using MWF on .net framework) it takes 3 clicks of the test button for the value to change in the Numeric up down control. I don't know why this is though.
