I've been seeing some very slow performance from MacENC for some time, but in the past few days it has reached the point that "no data" alarms are going off when I've selected nav on my autopilot. I do have an 8MB annotation file and hundreds of waypoints (most currently hidden) and I also record a track file on one minute intervals. Could any of these by the culprit?
Most of the alarms are generated when I change the chart scale, but yesterday I was getting alarms as I drove steadily across a small scale chart with no other apparent load on the processor. The alarm will go off two or three times in a few minutes and then there will be no trouble for several hours. Something definitely makes the program churn through some big delays. I've come to expect that scale changes will hang things up for 20-30 seconds (very slow screen redraws) but I haven't seen the no data alarms going off in the past.
Everything does work, just very very slowly.
