I still have problems using multiple displays, as I mentioned I have a laptop (resolution A by B) and an external display (resolution C by D). When I try to maximize the floting window out of the main window, it is either too small or too large, but never fits the actual resolution of a second display.

Yes, this is a known issue. The window is maximizing to a size based on the size of the screen in which the IRT task window resides. If all screens are the same size / resolution, no problems. But if the window in which the IRT task (main) window resides is larger or smaller than that of a floating window, the maximize command will not sure the window to the proper size of the screen it resides, but rather to that of the main IRT window. This is a problem with our underlying development tools and we hope to have a solution in the future. For now, you'll have to manually resize the window to get the maximized effect when you encounter this situation. Sorry for the inconvenience.

Ahh ok, thank you, good to know. I really like Investor/RT so this is just a small nuisance. P.
