Hi,

Reported by a user via Twitter: if a dialog powered by gui.messageBox opens, keyboard input won't be received by other NVDA dialogs.

Steps to reproduce:

1. Open NVDA's Python Console and type the code shown below.
2. After typing the code, press Enter.
3. Go to a browser window, switch to browse mode, then press Control+NVDA+F to find text.

The code to type from Python Console is:

import gui, wx
gui.messageBox("sometext", "somedialog")

And:

wx.CallAfter(gui.messageBox, "sometext", "somedialog")

Actual behavior:

Cannot find text in browse mode documents. When Enter key is pressed from find dialog, error sound is heard.

Expected behavior:

Find dialog works as advertised.

System configuration:

NVDA Installed/portable/running from source:

Installed

NVDA version:

Alpha.15693

Windows version:

Windows 10 Version 1803 and Insider Preview

Name and version of other software in use when reproducing the issue:

None

Other information about your system:

None

Other questions:

Does the issue still occur after restarting your PC?

Yes

Have you tried any other versions of NVDA?

Yes - 2018.2

Remarks:

Looks like we need to do something about message box differences between wxPython Classic versus Phoenix.

Thanks.
