They hath not the eys of mortal men.
The program was first released in 2003, and had several choices of colour scheme; text, window backgrounds. and the like.
In 2010 v.2 came out. The colour scheme was brown on brown., no choices available, not even an option to switch from light mud on dark mud to dark mud on light mud. A huge effort has been made to increase the loading on the graphics hardware, but the interface colours persist.
Fortunately, there is an alternative that uses human-compatible colour schemes. It is also something of a memory hog.
Since 2010 there have been changes to the major version number. So everything is OK.
