My apologies if this has been answered before or is intuitively obvious.
After upgrading to V4.60 64 Bit, IrfanView starts up with a random default file type like "All Supported Sound Files" or "XCF - GIMP File Format". All I Want is "All Supported Graphics Files".
This always happens after a reboot and sometimes even if IrfanView is closed and restarted. It never had this issue before the upgrade.
Thanks,
