I've been working for few months with QTP (UFT One 15.0.2), and today it has stopped recording (when I do the actions no lines are written in the script and no objects are added to the objects repository) and recognizing objects with the spy feature.
I am using the WEB add-in, and as I've been working for months with Mozilla Firefox I have checked that the WebExtension.xpi is well added to the browser.
I've tried to open mozilla before and after UFT One, I've also restarted my computer, I've checked the size of the screen browser is 100% and that in the Record and Run Settings the option " Record and run on any open browser" is checked for Web.
I have checked that I had the same problem with chrome browser, so not an Extension problem.
Finally I have decided to uninstall and reinstall UFT One, but while uninstalling an error appeared and UFT persisted on the system.
After two trys I have launched UFT One and it has started working again.
I am not sure how long it will work.
