Some time ago I started using lesstif on my Linux machine. I noticed that the progress bar looks like a slider. Is that intentional? On the cool side, the flicker is much less noticable than with Athena, which flickers horribly. Also, the `Stop' button does not seem to do anything. I don't know if that's lesstif-specific. Thirdly, it causes weird stuff in empty files. It might as well be a font-lock bug, but slider/progress-gauge makes it very noticable. Try opening a new .c file: C-x C-f ~/a.c RET Now start typing characters into it. What I notice is the bottom of the screen flashing like mad because a gutter forms to create a progress bar, and immediately disappears. The problem goes away once you insert a newline character. Either font-lock should be fixed so that it doesn't attempt to display the spurious progress, or the progress bar should be adapted to handle the case more gracefully.
