Disappearing TTIWAdvToolButton

D2009/IW10.0.23/TMS Intraweb 4.1.1

My main application form is for logon purposes.  On this form is a TTIWAdvToolButton.  For some reason, if I ever perform a WebApplication.Showmessage, the TTIWAdvToolButton disappears from the screen.  Have no idea why.
 
Any help is appreciated.  Thank you.

By the way, this continues to happen on any form which performs a WebApplication.Showmessage.  Very frustrating.

 
Any thoughts?

Retested this here with a form with a TIWAdvToolButton with the code:


procedure TIWForm4.TIWAdvToolButton1Click(Sender: TObject);
begin
  webapplication.ShowMessage('Hello world');
end;

and no problem can be seen here. Please provide exact steps / detailed information for allowing us to reproduce this.

Hi Bruno,

 
Could not determine why this was happening.  So, I rebuilt my forms from scratch and the issue has gone away. 
 
If it happens again, I will try to determine why the controls are disappearing.  One other thing, this was happening on all of my forms which used TMS Controls.  Very strange.
 
Thanks,
Todd
