vb.net 2010 async report not working in GUI - vb.net

Question

I know this is going to be virtually impossible to answer without me posting code, so I'll try to give some examples to aid this but...
I have a written dll which does some processing. I have it async tasks which report back status messages, such as the thing it's currently working on. There are multiple threads running each processing a different thing.
Now... when I use my DLL in a console app, the status.report("what I'm doing") works fine. I have a method in my console app with a Console.Writeline(text) which works great.
However... when I use the SAME dll in a gui form, and use the SAME methods from the console within the form to run the SAME processes with the SAME data, the SAME method that works perfectly writing the line to the console is NOT triggered and NO report is even processed by the gui.
Example.
console app:
Imports myDLL
Module Module1
Sub Main
SAE(paramaters).wait()
End Sub
Private Async Function SAE(parameters) as Task
Dim progress_indicator As Progress(Of Integer) = New Progress(Of Integer)(AddressOf DisplayProgress)
Dim progress_text As Progress(Of String) = New Progress(Of String)(AddressOf textProgress)
Dim complete As Object = Nothing
complete = Await Task.Run(Function() MyDLL.Process1(other parameters, progress_indicator, progress_text))
End Function
Private Sub DisplayProgress(ByVal percentage As Decimal)
Console.WriteLine("percentage " + Format(percentage, "0.00"))
End Sub
Private Sub textProgress(ByVal text As String)
Console.WriteLine("sub - reporting: " + text)
End Sub
End Module
Public Class myDLL
Public Function SettleAll(other paramaters, progress_indicator As IProgress(Of Integer), status As IProgress(Of String)) As Boolean
Dim aThread As Thread
aThread = New Thread(Sub() _OtherProcess(other parameters, progress_indicator, status))
aThread.Start()
System.Threading.Thread.Sleep(10)
aThread.Join
End Function
Private Sub _OtherProcess(other parameters, progress_indicator, status))
Loop
'Do Some stuff...
status.Report("Report back this it's working on this, that or the other")
progress_indicator.Report(SomePercentageProgressVariable))
End Loop
End Function
End Class
Now... when I use this, I get messages in the console window as I expect. However... in the gui... when I copy the SAE method and put the Sub Main code into a button click like this:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
SAE(paramaters).wait()
End Sub
... and I change the following methods:
Private Sub DisplayProgress(ByVal percentage As Decimal)
Debug.Print("percentage " + Format(percentage, "0.00"))
End Sub
Private Sub textProgress(ByVal text As String)
TextBox1.AppendText(text)
Debug.Print("sub - reporting: " + text)
End Sub
NOTHING at all happens...
The DLL is doing the processing, but there's no reporting.

Think I solved it.
If I change the button on_click method to an Async method llike this:
Private Async Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Await SAE(paramaters)
End Sub
It seems to work
