Description

If BlackBox is not restarted within 49.7days, you will find the caret of the text editor frozen, i.e. not blinking at all. The reason is an overflow caused by using an INTEGER for the ticks in Controllers.TickMsg instead of LONGINT.

My Patch:

1. Controllers

TickMsg* = RECORD (Message)
tick*: LONGINT(*INTEGER*) (** IN **)
END;

2. HostWindows.Idle

IF w.frame # NIL THEN
tick.tick := Services.Ticks();(*WinApi.GetTickCount();*)
w.ForwardCtrlMsg(tick)
END;

3. TextControllers.BlinkCaret

PROCEDURE BlinkCaret (c: StdCtrl; f: Views.Frame; tick: LONGINT(*INTEGER*));
