Thanks for your help. I am using a TImageEnMView and it seems to have a problem focusing sometimes. There is a third state between a thumbnail being selected and not selected. Two thumbnails are highlighed, one with the usual double line and the other just partially selected with one a one line border. Problem is intermittent. Any help would be appreciated.

Hi

Is it possible for you to advise the exact steps to reproduce the issue?

Also, does changing any of the selection properties affect it?

Thanks for getting back to me so promptly Nigel. My app has a ImageEnMView with thumbnails getting video refreshed 15 times a second. I have only one camera working so i have several blank thumbnails (black) and the one good thumbnail connected to a camera. Click into the "active" thumbnail and you sometimes have a problem maybe one out of 20 times. The new active thumbnail gets the focus and a red selection
rectangle of thickness 1. The thumbnail you are leaving still has the red section rectangle with a thickness of 2;

I changed the selection critereon EnableMultiSelect and got the same problem. What more can I change.

Regards...

Hi John

See if you can create a simple demo that reproduces it but without video dependencies (e.g. by using a TTimer to reproduce the video refresh).
