I just recently upgraded to the latest release of Rainlendar Light (Version 2.11 (b128) 64 bit). I am not using any 3rd party calendars, just the Task capability for To-do items. I have been using Rainlendar for years, so I'm not new to the product and solely use it for Tasks/To-do function.
Since upgrading a couple days ago, I've noticed that Tasks (with alarms) that I have created before (and after) the update to this latest version have a problem. The problem is when the Alarm for a Task activates on screen, right clicking over it and selecting "Completed" is not working. The Alarm continually represents itself and will not close the Alarm window on-screen.
The only way that I can get the Alarm window to close and go away (off screen) is to click on the "Dismiss All" icon that is part of the Alarm on-screen item. Rainlendar is
flagging the Task as "Completed" because I see the check-mark next to the "Completed" status, but the Alarm window will not close on screen. If I select another option from the right click list such as "Snooze" for x-period of time, the Task Alarm window will close properly. So it appears this problem is only associated with selecting the "Completed" status.
I just wanted to share this for investigation and thank-you for a truly great product!
