I would like to have a button over (or attached) to a pull-down menu that after user sets the field, the script performs a Go to object based on the choice made. As far as I can tell, there is still no "upon field exit, perform this script...".

I was trying to trick it into pausing the script with the pull down "open", then continue after field was set, but there is no way to avoid user mis-interaction on that method.

I normally would use bullet choices with buttons overlaid so when a user chooses the bullet marked Quotation I can fill in the field, set a few other fields and nowadays, Go to Tab Object, having made a tab for every bullet choice. Too many choices to use bullets in this new instance.

Any thoughts?

I have used a time delayed loop operation which pauses for 3 seconds to give the user time to select an item.

I tried a timer too, but didn't like what happens if the user doesn't choose anything. I ended up adding a test to see if the field was empty, then a test to see if the value changed from original state if not. I'd like it better if the PDM would show the active pulled down state, as it is now they have to click a second time to see the PDM.

I would suggest you look into using eventscript a free plug-in. It's available at http://www.softs4humans.com/FMPro_Plugins.html
