2002-03-22 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkgc-win32.c (gdk_win32_gc_set_dashes): Don't clear all of the pen_style, just the PS_STYLE_MASK. Seems to fix #74441, but that is just the special case of one-pixel wide one-pixel on-off dotted lines. To fully implement generic X11 style dashed lines a major rewrite would be needed.
