When summoning certain windows, I sometimes get additional pop ups that can't be clicked on. The transmit screen for a trade for example. Alt-tab(ing) doesn't work because the window disappears to the background when I do a mouseover. Enter button doesn't work eitherbecause the window hasn't been officially assigned to the foreground. An additional annoyance is the confirmation to close the alerts window. So, I am completely locked out from any other TWS window functionality. Just a beeping sound when i click the mouse. What causes this insanity? Pls help. Thanks.
