I had similar problems with other macros that deal with slices.
Perhaps not very elegant, but try to add a pause somewhere in the macro:
wait(200);
or something like that (you can try smaller/larger values and see if it solves
it). It helped in my case, so I presume that one command was executed while
the previous one hadn't released the lock). This seemed to happen in linux
but not in windows, but I am not sure why.
