Polar Diagram Gone Overnight

[bratters]

My polar diagram vanished overnight (when the PC is always switched off). Most annoying.

It started afresh OK this morning but was it just a glitch and has anybody else had a similar occurence?

Mine is still there ok. It happened to me once when a Windows update occrred overnight. My radarbox runs 24/7  and the system was shut down and restarted by windows. On restarting radarbox my log entries from after midnight had gone and the polar diagram started afresh.

it has happened since but never with any loss!!!
