Hi, sats,
If you're using PM Windows, you need to hack the registry at:
HKEY_CURRENT_USER\Software\Adobe\PageMaker70\UKENGLSH\PageMaker70
and
HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\PageMaker70\UKENGLSH\PageMaker70
and change the RGB settings for "RulerGuideRGB", "ColumnGuideRGB", "MarginGuideRGB", &c.
You may need to change the version of PM to "PageMaker65" and the language to your local lingo.
NOTE:
You are on your own on this one - make a copy of the registry before you start, as any foul-ups could mean Windows won't load and a re-install.
Iechyd da! John
