Hi Jeremy and welcome to the forum,
Are you using FileMaker Pro 10? If so you could give your first tab an object name, and then using the Script Triggers you run a script OnLayoutLoad that selects the first tab.
So the first thing to do is give the default tab an object name. You do this by clicking on your first tab, when it is the front tab, and a highlight will show around the tab, and then using the Object Info Palette, View > Object Info, give it an object name, so lets say "Default" for now.
Next you create a new script:
Go to Object [ "Default" ]
Now we have all the components setup we need to setup the script triggers, on you layout go into Layout Mode and then go: Layout > Layout Setup...
Click on the Script Trigger tab and then select OnLayoutLoad.
When the Specify Script dialog appears select your new script TabSelect and click OK and OK again.
Now go back into Browse mode and see if it works.
Not sure if there is an easy way to do this in anything pre 10, but you may be able to use script trigger plug-ins to do the same in 9.
Hope this helps.
Thanks for the welcome and the excellent advice. I am on FileMaker Pro 10, so all's well. Did as instructed, but set the trigger OnRecordLoad, so that it would do so each time we switch between records. All works fine.
No worries Jeremy, glad I could help.
You are quite right, it should be OnRecordLoad not OnLayoutLoad.
