The program hangs when TMSFNCWebBrowser components are used in two forms

[Roland_Cueni]

If only one FNCWebbrowser is used in the application, the application behaves inconspicuously.

But if another FNCWebbrowser component is used in a second form, it behaves conspicuously. The problem also exists if, for example, the TMSFNCWXHTMLMemo is used, but in the example I limit myself to the browser.

If only in the main form one or more FNCWebbrowser component(s) is/are used no problems occur - the response times are always ok for me.

Only when the component is also used in a second form, delays occur.
The following behavior occurs for me (sometimes only one of the two):

• The calling form can be served after closing the called form only after several seconds.
• After clicking the "X" (close) the program terminates only after a few seconds.

I have attached a minimal example project.

Can this problem be fixed?

The cache is shared and therefore it takes a while to clear the cache. If you don't wan't this, set a unique folder name for each instance:

procedure TForm1.FormCreate(Sender: TObject);
begin
  TMSFNCWebBrowser1.CacheFolderName := '1';
end;

procedure TForm2.FormCreate(Sender: TObject);
begin
  TMSFNCWebBrowser1.CacheFolderName := '2';
end;

With this approach, the delays are gone :-)
Many thanks
