GraphTask 4.02, which displays off-desktop programs in a multitasking task window, now includes a workaround for what developer David Ruck has claimed is a bug in RISC OS 6.14's handling of 256-colour sprites.

It's not what David claims to be a bug in OS 6.14. It's a bug that I found out by making some tests for David, i.e. that SWI OS_SpriteOp 15, when checking if it must create a 64 cols or a 256 cols palette, will create a 256 cols palette when your desktop mode in 256 or 64K colour mode and a 64 cols palette for other desktop screen modes.

This means that the SWI is reading some information from the current screen mode intead of the screen mode passed as parameter to the SWI.
