Hello, Within our application, users sometimes see a Red x at the location of the dropdown component. Then the application crashes.
This happens randomly, which means that we unfortunately cannot detect it ourselves from Visual Studio if we want to debug this.
We think it is because of the call from another thread:
this.Invoke (new MethodInvoker (() =>
var sRemoteParty = callHeldEvent.call.remoteParty.GetNameOrAddressValue ();
if (! btnResume.Enabled)
btnResume.Enabled = true;
btnResume.DropDownItems.Add (sRemoteParty, null, RetrieveFromHold) .Tag = callHeldEvent.call;
