dexvexpress AlertControl and Threading U.I freezes

hi i searched a lot in the forums but really i can't find a proper solution

what i am trying to do is simple

i have a forms splitted in 2, left side is a navigation bar (imagine something like outlook) and right side content. now every few seconds with the time i am checking for some data changes, and i wish to display those as notifications.

i have created an AlertControl just by code not on the UI designer, and i am trying to show the alerts on another background thread to prevent UI from freezing.

i tried everything but nothing works, my main UI on the left when the timer checks and trys to desplay the alert its freezes until the alert.show is done.

me.invoke me.begininvoke

i tried calling it like that to force another thread still freezes, i even tried the backgroundworker the same

plz any other ideas? thanks

Open in popup window
Dispatcher.CurrentDispatcher.BeginInvoke(Sub() ShowNotifications())

Open in popup window
Dim AlertC As New DevExpress.XtraBars.Alerter.AlertControl()
        With AlertC
            .AutoFormDelay = 5000
            .FormDisplaySpeed = DevExpress.XtraBars.Alerter.AlertFormDisplaySpeed.Fast
            .FormLocation = DevExpress.XtraBars.Alerter.AlertFormLocation.BottomRight
            .FormMaxCount = 3
            .FormShowingEffect = DevExpress.XtraBars.Alerter.AlertFormShowingEffect.FadeIn
            .AllowHotTrack = False
        End With
