Bonjour Peter,

Below is the handlers that I am using in my stacks (thanks to Éric Chatonet)

I just added the case 2 (corresponding to your need)
Here (MacBook Pro 10.0.8 ; Rev 5.0.2) case 2 seems to work, as you are expecting.

Best regards from Grenoble

André

on mouseMove
    switch
        case "button" is in the target
            ShowHandCursor #
            break
            ---====
        case "field" is in the target and the lockText of the target is true\
                and the listBehavior of the target is true
        ShowHandCursor
        break
    case "field" is in the target and the lockText of the target is false
        if the commandKey is down then
            ShowHandCursor
        end if
        break
    case the mouseText is "#" and the imageSource of the mouseText is not empty
        ShowHandCursor
        break
        ---====
    case the mouseText = empty --important!
        unlock cursor
        break
    case "link" is in the textStyle of the mouseChunk
        ShowHandCursor #

Setting "the cursor" will only be very fleeting, as the cursor will revert to the defaultcursor at the next idle message, and it happens so fast you never even see a flicker You can set "the cursor" then lock the cursor, then unlock it in a mouseleave handler, and that will work, but I learned a long time ago that this leads to persistent locked cursors, since LC seems at times not to send "mouseleave" messages, eg when a modal dialog is invoked, and randomly otherwise too.

I want to do the same thing over an unlocked field when the commandkey is down, to indicate to the user that a click is called for. I used to be able to do this, but now it doesn't work any more.   ????
