Great to see OpenCPN
continue to improve.
I might have found a bug in the handling of touchscreen dragging. The mouse/touchpad appears to work fine. When using the touchscreen, a (first) drag appears to move scroll the screen
in any direction appropriately, as with the mouse. However, a subsequent finger drag initially causes the screen
to jump back to the intial position, and then dragging continues. It is as if a touchscreen drag conclusion does not update the subsequent touchscreen "click" position.
Touchscreen seems to perform OK with other apps.
My PC is supposed to support multi-touch so I don't know if that is a part of the problem.
