cursor freezes in pcbnew after removing a corner of zone

[eelik]

I can reproduce this with a blank board.
1. Create a zone.
2. delete a corner of the zone.
3. Open DRC Control.
4. Start DRC.
5. Try to zoom with the middle mouse button. The cursor is locked to the point where the corner was deleted.

This may happen under some other conditions, too, because this cursor freezing has happened after doing something with zones but without running DRC. But as far as I can remember it has always involved something with zones. It has happened with several nightly builds from January, on Linux and Windows (although I just found out this one way to replicate it on Windows).

"This may happen under some other conditions, too"

And indeed, on Linux this happened with a board with one zone and one footprint. I removed a corner from the zone and then moved the footprint. After that moving the mouse doesn't update the coordinates and zooming happens on the point where the corner was.

I can add some observations on this bug.

1. Empty file
2. Create zone
3. Remove corner
4. Sometimes I get stuck cursor, but sometimes not. I get artifact that zone hatched outline stays around old perimeter.
5. Sometimes cursor gets stuck after some time on removed corner position.

I have reported this long time ago, hopefully its gone now

i keep my fingers crossed and pray because its been bad one, as it forced you to exit / enter pcbnew

i am on windows 10
will update to latest nightlies asap
