Issue I58 [gui,resolved] Ensure ESC key cancel actions in View screen. Reported by davidm. Description: Prior to 8.0.2, SIMION was ignoring the ESC key during long-running operations other than Fly'ms (e.g. 3D rendering of contours, view, and trajectories) unless focus was on the simgui (graphic) window. That prevented the user from aborting these operations. Affects: 8.0.0-8.0.1 Resolved in 8.0.2
