Safari Version 8.0.7 (10600.7.12) displays Top Sites rather than opening either old or recently saved Web archive files
iMac (21.5-inch, Late 2013) with OS X version 10.10.4 (14E46) displays Top Sites page rather than the Web archive file. I have tried multiple older Web archive files and Created multiple new files and when any of these are opened (double clicked, dragged on icon or selected from the file menu) the Top Sites page is displayed rather than the contents of the Web archive file.
iMac, OS X Yosemite (10.10.3)
