Ok, well here’s what I see in a simple test:
It check the Links Inspector check each link type your using on the map:
If ‘visible’ is unticked the link line won’t be drawn, and if ‘labeled’ is unticked even if the link is drawn the label won’t be even though the link still is of that link type in all other respects (e.g. for action code, in dialogs, etc.)
Does the problem affect all TBXs on your system, or just one/some TBX files? This is an important factor to help pin down the issue.
Assuming the Links Inspector is correctly configured, if you still have the problem could you upload or post a link to a small TBX that displays the problem. Please include in the TBX a note summarising the problem as you experience it.
