Why does adobe acrobat reader become gray in the following situation when using the escape key
1. Create a page with the following and make sure to load a pdf (replace sample.pdf with one of your own with Adobe Acrobat X 10.1.1 )
<html><head></head>< body><iframe id="IframeDocument" width="300" height="300" src="sample.pdf" />< /body>< /html>
2. Open the page in IE and make sure the pdf is fully loaded, now click outside the pdf ( somewhere in the whitespace )
3. Now press escape and adobe acrobat reader becomes gray.
Why does this happen and how to avoid it!!
