On our webview set up keyboard shortcuts and handle the command event.
We have for example a handler for F9 which evaluates some javascript on the page:
if (webView1.EvalScript("DoF9Pressed();") == null) {
// If this returns null it means that the js method "DoF9Pressed" is not available on the current document
MessageBoxEx.Show(this, "Job Search is not currently available", "Unavailable Option", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
When you press two keys simultaneously, for example F10 then F9 quickly (F10 is not handled) the whole application freezes completely like it's in a loop.
Can you take a look please, this is the same in the last few builds of EO (we always use latest version).
Regards,
Andy.

I've done some more digging and it's only F10 that does this. Also to note that if I add an F10 shortcut the application will not run at all?

Hi,
Is it possible that you can provide a test app to us? We tried to use our TabbedBrowser to reproduce this problem but we are unable to reproduce it. Our steps are:
1. Modify the code in NewWebViewItem to change the shortcut key from F11 to F9;
2. Modify the code in WebView_Command to run the code you posted (calling EvalScript and MessageBox);
3. Press F10, hold it, then press F9;
The message box displays correctly. Can you try the same steps and let us know if it works for you?
Thanks!

Hi,
Just built a test project and sent it to you. The error when trying to register an F10 shortcut is as follows:
System.Exception was unhandled
HResult=-2146233088
Message=F10 can not be used as shortcut because it's used by Windows to activate menu.
Source=EO.WebBrowser
StackTrace:
at EO.WebBrowser.WebView.set_Shortcuts(Shortcut[] value)

InnerException:
If I don't register the F10 shortcut it still hangs the test application, press F10 then F9 then F10 again a few times and you'll get it hanging.

Andy
