Just upgraded from 1.7 to 1.8, I'm having the same issue. Before
upgrading I ran blue background and white font. After the upgrade to
1.8, I now have a black background and green font. Going into
Preference | Options, my colors are correctly selected. White on blue,
but it's not showing up that way. I've un-installed, re-installed,
cleared out the registry and then re-installed. Nothing seems to
work.
One a side note, when I start up PowerCMD. For one very brief second
it flashes the correct back ground and font, but goes to green on
black
