>I downloaded Tlist 6.5 and it is working great, except for three things.
>1) when the control is in focus i cannot switch to another modal window. the tree control will not release the focus.

We don't use modal windows, so, we didn't experienced this problem. Probably, you should write to their support (it is very good and professional)

>2) when I use the arrow keys in the tree the second time i hit the arrow key the focus shifts to another control. I had to disable all the other controls on the form to prevent this from happening.

I don't see this... I set the control to follow MS Explorer behavior with key processing and it works just fine


>3) when I scroll vertically using the scroll bar it doesn't work that well. If I use the arrows at the top and bottom of the scroll bar it works as expected.

what do you meant by "doesn't work well"?
