I'm having a problem with the most recent TWS build. I can't describe exactly what I'm doing, but I click on a price, right click for transmit, and instead I get a message that I can't delete the row. Whenever this happens, the row above somehow gets highlighted. I realize I'm hitting something wrong, but I never had this problem with previous builds. It takes about 5 seconds to get out of this. This only happens on occasion, but I missed a good entry today because of this. Anyone else run into this problem? Def?
