I am beginning to think this all has something to do with my virus protection kicking in. In the past never had issues on any exeout versions with my virus / firewalls.
Have tested V2019 using two machines, one running standard windows security virus and other one runs Sophos Home Premium. They both act the same.
In V2019 when clicking save, can take some time and see the “not responding message” and then seems to save. For what it worth, seems to also happen when clicking update file structure.
When clicking the compile button, same behavior but seems to hang on different .php or .js files. Rarely the same files but always hangs. Sometimes it will continue after minute or so, other times I have to kill Exo4Php.exe with task manager.
If I completely disable my virus/firewall things return to normal.
Still troubleshooting the header location issue. Until I nail it down, do not wish to send you on wild chase. Will see what I can figure out and report back.
