I'm using the latest MBT Navigator software, and this problem occurs on two different pc's, both running XP Pro. Adding a symbol to the end of watchlist can cause that new symbol to appear anywhere in the list, top, bottom, in the middle, or replace an existing symbol. (I press INS, symbol and ENTER) If it puts the new symbol at the end, several blank lines get inserted. If at the bottom, there are hundreds of blank lines; scrolling with the wheel, or by clicking on the Up/Dn arrows on the scroll bar ONLY takes you further DOWN the watchlist. MBT's support guy was online with my pc, and could not figure it out. As I said, occurs on two different pcs, only similarity is both run XP Pro, with AMD Processors (one is single core, other dual), and use Zonealarm. Anyone else???
