This is my first time making a new post so my apologies if this is in the wrong place...
I'm running Creative Cloud on a Windows 7 machine. Since updating to CC2017, I've noticed that when tabbing through a scripted dialog box, it skips over dropdownlist elements. I've managed a workaround for my specific needs where I set an onChange function to the previous element in the dialog to automatically activate the dropdownlist I intend to tab to. This works, but it still doesn't highlight the dropdownlist as it did in the previous version.
I've had no luck Googling this so I'm hoping someone else is familiar with the issue and whether it's a known bug
That seems to be the way cc 2017 scripting ScriptUI works where prior versions would hilight the dropdown current item. If this is a problen for you report it to Adobe. Use submit a Problem in their Photoshop Family Customer Community
