We upgraded from 18.x to 19.0.69.

Now we are having the problem, that the component is crashing whenever any input in an textfield will occure.

We are getting the following error in the event log.

Anwendung: Viewer.exe
Frameworkversion: v4.0.30319
Beschreibung: Der Prozess wurde aufgrund einer unbehandelten Ausnahme beendet.
Ausnahmeinformationen: System.AccessViolationException
bei MS.Win32.UnsafeNativeMethods.DispatchMessage(System.Windows.Interop.MSG ByRef)
bei System.Windows.Forms.Integration.ApplicationInterop.ThreadMessageFilter(System.Windows.Interop.MSG ByRef, Boolean ByRef)
bei System.Windows.Interop.ComponentDispatcherThread.RaiseThreadMessage(System.Windows.Interop.MSG ByRef)
bei EO.Wpf.WebViewHost+a.c(c)

bei EO.WebBrowser.WebView+j.a(IntPtr, Int32, IntPtr, IntPtr, Boolean ByRef)
bei EO.Internal.z.b(IntPtr, Int32, IntPtr, IntPtr)

Does anybody know any solution to fix the keyboard input in the new version?

We have not been able to reproduce this problem. Can you try the latest build from our download page and see if the problem still occurs. We did change some code about input handling in our latest build.

If you still have problem, please try to isolate the problem into a test project and send the test project to us. See here for more details:


We will look into it as soon as we have that.
