I'd like to keep the user on the currently selected tab even when the user leaves for another record.

I have a script that identifies the currently active tab and another that restores that tab state.

I can trigger the latter via layout script trigger "OnRecordLoad" but how do I trigger the "memorizer" - even when no changes have been made to the record?

 

I am on FM11 so I don't have access to the new Tab-script behaviours.

My first thought would be to write a set of scripts to replace the go to next, go to previous and go to...menu items. however FM 11 advanced is required. You should probably upgrade because FM has ended official support for FM 11 product line.

If you go to another record in the same layout, the tab selection does not change. Did you mean "leaves to another layout" or something similar?

 

In any case, you need to trigger the "memorizer" when user changes the tab selection (by attaching an OnModify script trigger to the tab control object).
