Hi Cinc-th, perhaps could you tag another stable version including this fix? I don't want to force the people to use the trunk. Currently, I cannot find the time to do this by myself. TIA, falkb

[Cinc-th]

Hi falkb,

yes, that may be worthwhile. There are also a few new features by now. I put it on my Todo list.
