Viewfile macro's dropdown menu doesn't show the selected file name in IE8

The dropdown menu of the viewfile macro which displays the list of attached file names is not displayed as intended. The menu does not show the selected file. This is only a display issue and it does not affect the functionality of the view file macro itself.

Note that this is NOT reproducible in Windows XP, IE 8.0.6. This was tested in Windows 7 32-bit IE 8.0.7

Steps to reproduce:

• Upload some Office attachments (Word, PowerPoint, or Excel)
• Create a new page (or edit a page)
• Try to insert one of the viewfile macros to display the Office attachments
• The dropdown menu is not displayed as expected when the file is selected
