Getting blank window

[bennyAG]

Just before the file download dialog box appears i get an open empty window that i can close.
There is also an error coming from the library:

Uncaught TypeError: Cannot create property 'href' on string 'about:blank'
pdfmake.min.js:2

Some has a clue?

It also happens with minimal code see:
docDefinition.content = [];
docDefinition.styles = {
smallText: {
fontSize: 7,
},
filter:{
fontSize:12,
color:'red',
}
};
pdfMake.createPdf(docDefinition).open();
pdfMake.createPdf(docDefinition).download('search.pdf');

You have to use open() or download(), both do not work at the same time.
And download() works on all browsers, open() not. See supported browsers: #800. In Chrome works only with disabled AdBlock.

Not sure it was clear from the instructions.
But thank you for the fast response.
