When drop files monitor opens window to select files

Hi to all

I updated to version 1 and get same response as version 0.9.9

With monitor open and disabled printing when I drop files before show droped file automaticaly opens window to select new files. This happens also when resising columns.

There is any way to disable this action? I not found any option about this.

I'm running PDFCreator on a Vista Home Premium.

Thanks for your help
