Unable to "Select All" for uploads

Hello
I upload groups of pictures to my company's server to accompany a written report using IE9. In the past after login to the server I would browse to the picture source and and "select all" for the up load. Two days ago this feature stopped working and select all is grayed out. This requires me to upload pictures one at a time.
While shooting this I found the feature works with FF and works with other programs on my box. (Vista 64, updates current). I have to use IE because of a proprietary drawing program my company uses. I have not made any changes to my PC.

Thanks for the help
VV
