Clearing all spots causes an Access Violation

[ny4i]

When right clicking on the spot window and clicking to remove all spots, the program faults with an access violation.

The place this stops is in uSport.pas at line 382

function TDXSpotsList.Get(Index: integer): TSpotRecord;
begin
  //  if (Index < 0) or (Index >= FCount) then Exit; //ERROR(@SListIndexError, Index);
  Result := FList^[Index]; // This line faults. It appears that FList^ is not a valid pointer. Try...except?
end;

Thanks for your detective work Tom.

I enabled the commented test, and that circumvents the problem. I will shortly upload beta-1

Am sure Gavin is in Z land, but perhaps he can review tomorrow.

This is a strange one, I have been trying to replicate on 4.46.beta and it was all fine until I deleted an individual spot, then did a remove all spots.

Will have a look tonight

Can this be closed ? Tks, Howie

I saw a related issue. When I cleared the band map, the display changes to strange characters momentarily. It's as if the band map is cleared but a final display shows strange characters.

I am sure this can be closed

I will turn this into another one then. The flash of garbage characters is a bug. I was thinking since it was related to clearing all that we could use this issue but it’s easy to open another one.

Thanks,

Tom
