The clock option doesn't work any longer with my files nor with the example 3 file of the ctan distribution of powerdot. The problem arose after an MiKTeX update. Formally the files compiled with the clock option, now the file compiles only if the clock option is omitted. Does anybody know about this problem? Is it a powerdot problem or an xcolor problem?
