Speech viewer window is inoperable when Elements List dialog opened

[patrickhlauke]

Steps to reproduce:

• open NVDA
• open Speech Viewer
• subsequently, open Elements List dialog on a web page

Actual behavior:

The Speech Viewer window becomes inoperable - can't be moved, text inside it can't be selected, the "Show Speech Viewer on Startup" checkbox can't be operated, nor can it be closed with the "X" button top right. It's also always on top, so obscures underlying content/dialogs/etc, but can't be moved out of the way. Only once the Elements List dialog is closed can the Speech Viewer window be operated as normal again.

If you have Speech Viewer mapped to a shortcut key (in my case, NVDA+S), it is possible to close the Speech Viewer and then re-open it. At that point, the Speech Viewer window is operable as normal, even with the Elements List dialog open.

0:00 opening Speech Viewer 0:09 opening Elements List dialog 0:09 - 0:22 clicking on the Speech Viewer, trying to move it, tick the checkbox, etc 0:23 clicking onto Elements List dialog, disabling Speech Viewer via shortcut, reopening it 0:26 - 0:29 Speech Viewer can now be dragged/clicked/operated

Expected behavior:

The Speech Viewer window should remain operable even if launching the Elements List dialog.
