Why do the colours flicker or not get set up properly?
Again due to use of 8 bit colormaps as the inheritence of colormaps from child processes was never fixed for these on some systems. The software generally works fine on UNIX platforms and will work after a fashion on LINUX running fvwm2. Forcing a Tv panel to full draw the displayed image generally fixes it though the number of colours required by the desktop should be kept to a minimum. The best plan though, is to to upgrade to the new TINA version which has support for 16 bit colormaps.
