This might seem like a daft question but is there a memory limit on DF 64 bit applications ?

32 bit is obviously limited to 2gb

64 bit has a limit of about 184gb

So if there is a memory leak in a 32 bit application it will fall over when it gets to 2gb and most PC's these days have at least double this in RAM so are probably going to keep going OK

But a 64 bit application would just keep munching memory until there is none left and therefore quite likely to bring the workstation to a halt ?

Just thought I would ask
