Mouse Update NullReferenceException with quick pointers

[Ecks]

Had this happen during a session when using quick pointers and was able to reliably recreate it in a new 5E campaign with no extensions.

To recreate:

Open up a map (I'm using one from Tomb of Annihilation)
Draw a quick pointer (with Left+Right click): Capture1.JPG (https://www.fantasygrounds.com/forums/attachment.php?attachmentid=51044)
Position mouse cursor here: Capture2.JPG (https://www.fantasygrounds.com/forums/attachment.php?attachmentid=51045)
Left+Right click in this spot to clear the pointer, then release without moving/drawing a new pointer. Pointer disappears (as expected) but with the exception pop up

I can provide the compiled logs if it'll help.

I raised this with FG support a couple weeks ago

JPG replied via email; it should be fixed with the next client update, 2-4 weeks from 6 days ago they said.
