When selecting a column of text using column select, if you only select vertically, you see a blank column at the selection. once you unselect the selection the text is still there correctly, it is only wrong while selected. If you select horizontally as well as vertically you get a highlighted selection box.
eg: sample text
XXXXXX
XXXXXX
XXXXXX
sample text vertically column selected at the 3rd column without any horizontal selection.
XX XXX
XX XXX
XX XXX

Column Select Bug in v3.96o
What RGB color values do you have defined for your fourground and background marking region 
You can find this out by going to the Document Type, Color panel, selecting the Marked Area option, then double clicking on the color square.
In the old Zeus when you select in column mode there is no indication of an active selection. With this version Zeus will simulate a column selection by crearting a color that is close (but not identical) to the current marking colors.
What might be happening is that because of you current marking colors, this simulated color might be somehow overflowing the RGB ranages
You could also try altering your current marking color.

Background selected colour is white, foreground selected colour is black
Standard background colour is black, foreground colour is white.
I changed my marked text colours, and when I did the test selection, the blank line came up as an inverted marked text background colour with the marked text foreground colour unchanged.
With my normal colour selections therefore, i get black on black.
