Quick Look in OpenFileDialog now working in existing project

For me, it’s repeatable with all code posted here, including my simplest:

call FolderItem.ShowOpenFileDialog( "" )

But here’s the key for me. If I don’t first left-click to select a file, it fails. Right-clicking any file without left-clicking any file causes the problem. Once I left-click a file, it works as expected to that file or any subsequent right-click. Though the selection changes, it’s like it never realizes it from right-click until a left-click happens.

Unfortunately, my project is quite large and complex. Since the MBS method OpenDialogMBS fails, too, I’m willing to believe it’s some setting in the project, but there’s nothing obvious.

Also, unlike Anthony, left clicking on the item first doesn’t help. I still get that error.
