Okay this is very minor, but upgrading to HP TRIM 6.2.4 1240 yo can no longer search lists by typing. Highlight location/folder or object and start typing. The functionality is still there in Windows though.
Do you mean the 'Prefix' search box that pops up when you start typing while in the Location list for example?
It is still there and should work, but I have seen some sites lose it for some reason.
Try resetting all toolbars/UI.
Also try a get global.
And eventually a reinstall of TRIM.
I've seen some cases where it looked like the Intel Graphics drivers were causing the problem too...
