Select you transition and, with the mouse cursor, move the transition outside of the Transition "Drag and Drop a Transition Between Clips" display. The display will close. Then you will have a clear view of where you are heading on the Timeline.
Please give that a try and let us know if that works for you.
If you want to apply the same transition across all the clips on the Timeline, then select all and then Timeline Menu/Apply Default Transition.
Please let us know if the above works for you.
Many thanks ATR, yes that does work! Jammyone
Thanks for the reply with the good news that the suggestion worked for you.
Also, did you know that some of those display palettes (includes Transitions one) can be enlarged by dragging upward on it with the mouse cursor to give you a better view of the choices?
Yes, I'd worked that one out! Thanks again
