Thanks anthony Just to clarify: the problems are in the browser, not in pyjamas desktop. And yes, your hint was correct. Removing the public/Portal.html got rid of the issue (just removing the bootstrap.js line was not enough) I am a bit worried that I will need that file in the future. Currently pyjs is doing a good job including my public/Portal.css in the generated output/Portal.html file, but I am not sure if other custom CSSs will be also included automatically. Besides, it could be that I need some custom javascript, so that the public/Portal.html file will be necessary. In a related note, I have seen that pyjsbuild is cluttering the output/Portal.html file: <script type="text/javascript" src="bootstrap.js"></script> <iframe id="__pygwt_historyFrame" style="display:none;"></iframe> <script type="text/javascript" src="bootstrap.js"></script> <iframe id="__pygwt_historyFrame" style="display:none;"></iframe> <script type="text/javascript" src="bootstrap.js"></script> <iframe id="__pygwt_historyFrame" style="display:none;"></iframe> This has no effect apart from slowing down the loading of my application. The only solution I have found is to delete the output/Portal,html file each time before calling pyjsbuild. BR, Daniel
