nkny,
you came across a bug that should have been resolved the other day. It had to do whether you dragged or clicked on the mouse when you changed a buy to a sell. It should be resolved by now.
mc98,
Regarding the calls to click on the bid for buy - I doubt it will happen. The idea behind the IB workstation is speed. If you are lifting an offer or hitting a bid speed is essential. Giving the choice of one or the other may lead to confusion and erroneous traders.
As for the other suggestions, like the time delay an order stays on the screen. I agree it would be nice to make the time a variable. If you want more functionality on the hot keys, please request it via mails to ibmgt on the web site.
As always, I'll try to pass your comments along. NKNY, if you have had the problem with the order line again, please send me a mail so I talk to the programmer who worked on the fix.
