Only two and a half years after the last release, here is version 1.7 of TrayBlank. I didn't bother releasing version 1.6 because it only added one extra option, a slight delay before the screen saver starts.
Version 1.7 adds an extra hotkey for configuring the screen saver, and there are now checkboxes in the hotkeys setup dialog to enable/disable each of the hotkeys individually. I added this after I found myself turning the monitor off accidentally a couple of times.
The new version of TrayBlank is available from the downloads page.
