Modules & VBA :: Stop Controls From Flickering When Timerevent Fires?

Is there a way to stop the controls from flickering when the timerevent fires?

What doesn't work:

Code:
Application.Echo False
Docmd.Echo False
TimerEvent on the current form
TimerEvent on a different form

Using Windows API:

Code:
Private Declare Function SetTimer Lib "user32" etc
Private Declare Function KillTimer Lib "user32" etc

Each of these events flicker the controls on my forms. The effect is worse when the form background contains a picture.
