I've got two unrelated questions:
1) I recently saw a statement on this newsgroup which talked about turning
off the "refresh" of a PANEL_LIST so you could insert/delete/change items
without flicker. The solution posted was:
xv_set(aList, PANEL_PAINT, PANEL_NONE, NULL);
/* inesert/delete/change list items in "aList" */
xv_set(aList, PANEL_PAINT, PANEL_CLEAR, NULL);
I've tried this, but no luck. Same old filcker...
2) I've got a tty_sw that won't echo characters typed in the window. Output
to the window is fine; input is ok too, except I can't see what I type.
If anyone has any ideas, or needs more info, I'd appreciate it.
