User-defined event crashes TwinBasic

Hi TwinBasic team. You are appreciated!

I found an issue with TB. Perhaps already known. The following code causes TB to keep "Restarting From Memory" when trying to run in the IDE.

Binary build completes successfully but fails silently and will not run.

Code:

 Private Sub UpdateColorInfo()

        

        Dim nH As Single, nS As Single, nL As Single

        txtInfo(0).Text = "&H" + Hex(lblCurColor.BackColor)

        txtInfo(1).Text = Color2Long(Trim(txtInfo(2).Text))

        txtInfo(2).Text = ColorToHTML(lblCurColor.BackColor)

      

        RaiseEvent ColorChanged '<-- This crashes TwinBasic.

    End Sub

If I rem out that event call, then all is well. And there is nothing special about the event declaration. Further, the event is not being used outside anywhere

I've also noticed that TB does not always fire certain valid events, including some which are baked into VB6 intrinsic controls.

Anyway, hope this is helpful. Keep up the good work :).
