The workaround is simple. Use Cronnix (freeware) to create a crontab that launches Retrospect at a specified time. Here is an example of my cron entry for Retrospect:
Min 0 Hour 1 MDay * Month * WDay *Note: shown on three lines, needs to be one line ... this launches Retrospect every day at 1:00AM, which is perfect since my backup script launches at 2:00AM.
Command /usr/bin/open "/Applications/Utilities/
Retrospect 5.0/Retrospect"
BTW, now that you know about Cronnix, you may find it useful for other tasks. I also have it launch my Calendar every morning at 6:00AM, so when I get up it's the first thing I see on my screen.
