Workrave seems to start when my computer is turned on, but the timers, and thus notifications do not always run. Often I'll click on the workrave icon and the timers will show and then start - but no break notification takes place afterwards (i.e. after the specified elapse of time). Some days, Workrave works well, notifying me to take a rest regularly and as programmed. Unfortunately, it seems to be fail to work more often than it works.
