Hi
Can't say but this works for me...
Position the slider
Press the + on the overlay tab. This opens the "New Overlay" pane.
Check the "Text" radio button.
Click the pane then type your text and click OK.
Your text should now appear in the overlay track on the sequence line as well as have an entry in the clip list.
Left click the overlay on the sequence to open the control panel for your text.
Change font/position/size/fade etc. as required
You can also reposition your overlay by dragging it along the track.
