Details

This bug is sporatic "the worst kind", has effected a 4gb fuze+ "foolsh in IRC" and an 8gb fuze+ "DmL in IRC", but also has been confirmed to be absent from one other 4gb fuze+

Rockboy data aborts on menu key press, when the srceen is rotated left and image is stretched across the whole srceen. Also no matter what key is mapped to the menu entry it will still fail.

It never fails when aspect ratio is maintained with scale or when not scaled at all, and never aborts when rotated right or not at all.

Only four files even mention rotate in the apps/plugins/rockboy/ directory "lcd.c menu.c rockmacros.h and sys_rockbox.c"

Sometimes the failure does not happen and reaching the menu is possible, but the rockboy option file may get written and not allow the user back into the menu later to change the rotate option back. When this happens the option file must be edited or erased to make rockboy work again normally.
This task depends upon

EDIT: it seems to effect all Fuze+ players the confirmed one (above) that did not have this issue was wrong it does abort like the others

NOTE: The fuze+ simulator does not exhibit this behavour and works without error rotated left and stretched.

DmL suggsted it maybe the in options file of rockboy. So by setting the same options for two files with only scaled and scaled with aspectratio maintianed being the differnace, yeilded nothing apparent. Only one bit was changed, output of dhex attached.
