A bug with Magnifier view freezing and a logged error.

This occurred twice to me (on 2 different PCs). First time after a long time of use (more than 10 min). Second time (this report), quite immediately after NVDA startup.

Steps to reproduce

• Launch NVDA
• Start Magnifier
• Set zoom and color filter as needed (I use inverted colors)
• Open Notepad
• Type in Notepad or move the caret in it with keyboard keys, e.g. arrows, home, end, etc.

Actual behavior

A a certain moment, an error is logged:
_ctypes.COMError: (-2147418113, 'Défaillance irrémédiable', (None, None, None, 0, None))

And the magnifier view freezes, i.e. does no longer follow.

Exiting and reenabling the Magnifier fixes the issue.

Expected behavior

No view freeze.
