Incorrect jump to a position marker...

If during playback of a CD card show jumping to a position marker fails and show playback keeps starting from the very beginning...

Reason: Jump markers in CF card shows do not support position markers as jump destinations.

Possible solution: Create a second show and copy and paste the corresponding part of the first show to be played into it.  In the first show, instead of the jump marker use a special functions marker with a jump into the second show as the corresponding action. See Special functions marker.
