I have two forms with TTMSFNCWebBrowser component, they both work but when the two are open together upon closing one, the application (main thread) does not respond for 3-4 seconds. If I only have one form open and close it, then it is fine.
D10.4
FNC UI Pack 6.8.1
WebView2Loader_x86.dll 1.0.3124.44
Do you have a small reproducible sample?

There is a small delay like half a second, so it's system dependent, but the reason is that when closing a browser instance it cleans up the cache. If you don't want this, set AutoClearCache to False
procedure TForm1.FormCreate(Sender: TObject);
begin
TMSFNCEdgeWebBrowser1.AutoClearCache := False;
end;
Thanks, that works great
Let me know if anything comes up
