Dojo Tooltips missing the mark sometimes

I'm using tooltips for icons that are displayed in a dijit.Dialo开发者_StackOverflow中文版g. Sometimes they work just fine, but other times they get placed around 25 to 50 pixels further away from the target than they should be. I can't see any pattern to when this happens. Any ideas on why the screen placement would be varying in this way?

Thanks,

Karl

you can use dijit.showTooltip and dijit.hideTooltip. Here is an example on how to show tooltips on complex dijits such as FilteringSelect and ComboBox with this simple techinque
