C# MessageBox doesn't display the whole string of text anymore

I am trying to display a simple message, which I have done probably thousands of times in the past, and NOW... The full string of text is NOT being displayed in the MessageBox. I'm not doing anything differently, so I don't see the problem. Here's my code:

if (MessageBox.Show("The text in this file has changed. Do you want to save changes?",
    "TextEditor - Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Hand, MessageBoxDefaultButton.Button1) == DialogResult.Yes)
{ //Do stuff 
} else { 
// Do stuff }

Now, when the messagebox is displayed, the only text that is visible is this:

The text in this file has changed.

NOTE: The Yes/No buttons are visible, and the messagebox looks normal, it doesn't look broken or anything, so I have no idea why I can't display a simple dam question in there anymore!?... Does anybody know about this? Have you experienced this before?

Thanks

OK, THIS IS WIERD... (EDITED)

I have just changed the text for the above messagebox text and now it displays the following:

The text in this file has changed. Do you wa

But the most important part of the question is still not being displayed...

Solution

I have just solved this problem. I am using Windows XP Home Edition and am also using Stardock's WindowBlinds to pretty-up the 500-year old WindowsXP interface. This has never caused any problems in the past, I have been using WindowBlinds for years, and also doing C# stuff for about a year and a half, and this is the first time that WindowBlinds has caused any problems what so ever.

The reason why only part of the text was showing in the MessageBox still ramins a mystery, BUT as soon as I decided to try and Close WindowBlinds and apply the standard XP theme again... All MessageBox's work properly in C#.

Thank you ALL for your good suggestions they are very much appreciated. :o)
