Thats reminds me the example of the Drawtext which comes up in the box when you type .Drawtext is wrong. It has an extra parameter in it at the end.
It confused me for a while as I tried it with the exact fields as shown in the example which has (...,"LEFT",5) and its says too many parameters. The last number is not required.
Maybe Erel is already aware of this but just mentioning it as worth fixing the next release.
