Hi,

I haven't tried to disable "drag and drop" in normal mode. According to the information in this link, it's possible but you would need some serious hacking :

However, if your browser uses the "off-screen" mode (OSR) then you have full control as you can see in the SimpleOSRBrowser demo. All events and dragged information are available.

Remember that the current CEF4Delphi version has a known issue resizing the browser window in OSR mode :

Thanks for reporting this issue!

Please, provide a complete minimal code example to reproduce it.
