I noticed a problem in OpenCPN
4.4 that was not present in 4.2. If you open the Track Properties dialog (for example, by right-clicking on a track and selecting Properties...) and click on one of the track "recorded points", then try to use the keyboard up or down arrow keys to scroll through the list of points, the chart pans instead scrolling through the list.
This used to be a nice feature in 4.2--you could "play back" a track by holding down the keyboard down arrow, and the Track Properties dialog would scroll through the recorded points as the chart stayed centered on the location of the then-current point.
Now (with 4.4) as soon as the keyboard down arrow is pressed, focus changes from the Track Properties dialog to the chart, and the chart scrolls to the south.
I would appreciate it if you could put this on the list of things to be fixed in the next update.
