Refresh Microsoft Office Chart 10

[Dan R via AccessMonster.com]

Hi

I have a Microsoft Office Chart 10 on a form and I am trying to refresh it in
VB with

Forms![MainForm].[GraphName].Refresh

This works most of the time. But in roughly one of four cases I have to run
this command several times for the graph to refresh.

Any ideas what could cause this strange behavior?

Thanks,
Dan
