The BSTLbG global extension must be added if you want to use the new Stretch Text feature that enables text to be spread across multiple cells in vertical or horizontal (Booking) scheduling formats.  You must add it to each app in a multi-dll application that you want to use the feature in.  The Global extension makes the BSTListBox Class available to all the procedures in each app.

Adding the global template makes the stretch text prompts available in the applicable templates.  Clicking on "Disable BSTLb in this App" will disable all code generation in regards to the BSTListBox Class if you are suspecting a problem related to it.
