Window sizes when changing resolution

Hello I don't know, maybe it's a bug, maybe some misconfiguration but I have a question is it possible to fix this problem: I am using TDE 3.5.13.2, Debian Wheezy, running on Dell D430 subnotebook. This small computer has 1280x800 LCD, Intel GMA chipset. At home I'm docking my Dell and redirecting video using xrandr to external monitors: two 1600x1200 displays connected to dock's ports. The desktop is split on 2 monitors, the system menu/task bar is shown only in the left one, exactly as I want. The problem begins when I hibernate computer undocked and unhibernate it in a dock. It of course still shows picture on internal LCD, so I have a script with xrandr to set proper resolutions and settings. After changing resolutions and displays, Most of resizeable windows on screen become one screen (1600 pixels) wide. In this situation, the next one happens relatively rare: Konqueror's window sometimes have decoration placed higher than screen, so it can be moved or closed only from task bar menu. Is there any option in configuration to prevent this window expanding when resolution is changed? Shrinking works and is OK (it must be for reverse situation - undocking). MCbx
