Rainlender is excellent, best software of its type I have used. (Version 2.11 (b128) 64 bit - I don't need the advanced functionality of the Pro-version).
Only problem I have is with Alarms: I have several tasks with 'Recurrance', some two weekly. some monthly, a few every 3 months. Each is set to a reminder Alarm only a few days in advance.
If an event has gone beyond the 'Due Time', occasionally (not every time)I get an Alarm message such as 'Due in 13 weeks, 6 days, 22 hours' even though the Alarm reminder has been set at 5 days or similar. This seems to happen even if both the Task and Alarm have been marked as completed.
I have tried deleting these Tasks and creating new ones with the same information and all is OK for a while, then another 'Recurrance' tasks pops-up well in advance of the reminder date.
Additionally, if I try to 'Snooze the Alarm' to something like '7 Days before the Due Date' it just reappears and I can only get rid of it by 'Dismissing'.
Any ideas what I am doing wrong?
