apps/graphics/tmw4nx and apps/graphics/slcd: This seems the last of the show stopper bugs. All seems functional.
apps/graphics/slcd: Correct some errors found in early texting. Now the Twm4Nx::CClock window comes up, but there are problems with the way that the segments are being displayed.
apps/graphicx/twm4nx: CClock is complete and compiles correctly. Crashes with a hardware when the clock is selected from the Main Menu, however.
