For the past few versions of TWS, I'm getting market data lines with very light-colored question marks "?" in any line that doesn't produce market data. Or, in a market data line that should produce data, I'm still getting question marks showing up. Is anyone else experiencing this? I'm running the current version and can't seem to figure out why this is occuring. Haven't talked to cust support yet as I never seem to get thru to anyone. Thanks in advance.
