Data Difference - TS4 vs TS2K

["ndtrader" <ndtrader@xxxxxxxxxxx>]

Here is something scary.  I just set up my TS2K for RT alongside TS4,
identical BMI feed.
Last night 12/28/01 between 1:37am and 1:42am TS4 shows the following

SP2H: no ticks, prices before and after around 1161.50-1162.00
ES2H: 2 ticks of 1161.50.

However, TS2K shows the following between 1:37am and 1:42am

SP2H: 15 ticks around 1157, prices before and after normal
ES2H:  67 ticks around 1157, prices before and after normal

I would have never caught this but the charts certainly look different.

Does anybody has, or has had this problem?
If so, what should we do about it, other than stop worrying and learn to
love Trade Station?

Thanks.
