If you look carefully in the first screenshot you can even see that the phone icon is fully rectangular. There is a slight difference in color at the bottom of the rectangle.

I have a form with a ToolStrip with a number of  ToolStripButtons.  For a button that I just added, when I hover over it, the image takes on a different "background" color than the text area of the button.  For a button that was already on the toolstrip, this does not occur.  See two image.     Can anyone tell me why my new button does this, and how I can correct?

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight.
