Dialog box bug

The dialog box is hidden if more than one file is selected when the script is run. It brings up a progress box and then the dialog box is pushed behind all the screens. It did this in Opus 12 too, but the dialog box was still visible just behind the progress box so i could just click it, but now it completely hides it where i need to go to the taskbar and click the opus icon to bring it back up.

Which dialog box do you mean?

What is the script?
