We've found and fixed the Windows 2000 problem with this method, it will show up in build 673, which should happen by early next week. Thank you for everyone's patience on this issue.
When i pull in TS data and use item.lSize I usually get a valid lot size ie. TradeSize or Volume for that trade, etc. - although the first couple of TS data inputs you receive & pull in will sometimes have 0 for lot size.... handle/cache issue or something maybe...
