It is this bug: https://bugzilla.novell.com/show_bug.cgi?id=621475
I submitted a patch for it, but it hasn't been applied yet.
> I apologise if this has come up before, I used the search but found

> I have a text box which starts off with text in it, then when the user
> clicks, it uses the click event to remove that default text - allowing the
> user to enter their own without having to delete the default text
> However, running under Mono (2.6.7), when I click on the text box control

> I tried creating a new Solution in VS2008, stuck a text box on the form.
> The only property I changed was the "Text" on the TextBox control which I
> changed to "Hello".

> textBox1.Text = "";
> textBox1.Text = string.Empty;
> textBox1.Text = null;
> However, all of these cause the form to simply close after clearing the
> text from the box.
> Interestingly - if I add something like this:
> After the line for clearing the text box then the form doesn't close after
> clicking. It brings up the message box and then gives you the cleared text
> box to enter into what you wish, and remains usable.
