Yep that's the issue. For me it opens two windows of the same proof, so that I end up with three tabs open. Sometimes it seems the new proof will not upload correctly if all the tabs are open. I have a greater incidence of proof fail. I do close the extra tabs most of the time but if you are working...

Has anyone figured out how to stop multiple tbs from launching when you open a proof?I get 2-3 new tabs each time and sometimes it causes issues when uploading a new version of the proof.I am using Chrome. Workfront has more issues if I use firefox. I don't have Safari installed.
