-Wshow:


Dviout invokes METAFONTS for font generation and Ghostscript for PostScript interpretation etc. These external programs are run in an iconified state (hidden in the Windows task bar, not as an open window) by default.

If the -Wshow: switch is ON, external programs are run as a separate window, which is open until the program ends (Property Sheets->[System]). This switch should be set ON if the program stalls when iconified state.
