Today under a delphiCef4:87.1.6, with a look of it under delphixe10.3 example:
"Delphicef4 \ demos \ Delphi_VCL \ SimpleBrowser2"
Found a strange question, visit https://mail.163.com after exit would be an error, and sometimes there will be a process remain, checked the online information, added GlobalCEFApp. QuitMessageLoop; No matter use, access to other website is no problem,

Excuse me each bosses, this how to solve?
