Light settings do not work on Mac
Adding vector data crashes wxGUI on Mac
Rendering at fine resolution works only when changing viewing position or clicking the buttons that increase the numbers for perspective, twist, height and z-exag. Moving sliders does the required change but there is no redraw to full resolution
Viewing height sometimes sets to 1 after switching to 2D and back to 3D View (or with the simultaneous 2D view - very nice feature) and even after View is reset, it keeps getting back at 1 each time the slider is touched
Typing in the height or z-exag numbers and ENTER does not do anything but the typed number gets accepted after clicking on the increase/decrease button, it is not possible to set the height value beyond the initial maximum
Adding fringe just flashes it but it does not stay
Isosurfaces tested with Nags Head time series data (I will provide link) don't seem to be working, after setting 3D region and adding 3D raster nothing gets drawn, when moving the related DEM around only line rectangle shows instead of a box.
Adding draw, draw current and clear button may be useful
