I'm using 4.3.0-42 and have noticed that the following minor bug in multi-window operation when running on Win2K and WinXPPro:
Two windows (terminal or otherwise) are overlapped and the topmost one has it's "Always on top" attribute set (by right-clicking on the windows title bar). The topmost window is then minimised, leaving a copy of its contents on the desktop, viewable by moving the remaining window over the portion of the desktop previously occupied by the other window.
