I was trying to reproduce the problem, but without luck. I've installed MSVDM. I run WinSCP. When I switch desktop, tiny window title of WinSCP appears next to "start" button. This is known bug, that I do not know how to get rid of. But when I switch back to desktop with WinSCP window is restores to original size. No reducing. Do you do something else?
When I switch desktops and then switch back, sometimes the WinSCP window is now the tiny window title box, descibed earlier. It is not by the Windows start button, but where the original window was based on the windows upper, left corner. Note, I set the taskbar to the right screen edge vice the standard bottom creen edge, so the Windows start button is upper, left corner of the desktop.
I have tried minimizing the WinSCP window before switching desktops, and this seems to produce better results. I have been trying to determine if the chronic nature of the resizing can be traced to some action or application but have not been successful yet.
Sometimes when I launch a new instance of WinSCP before closing the tiny window title box, the new instance is the same size as the original window, and sometimes it is much smaller. I have no idea why. :roll:
I am running PuTTY beta 0.58, we are on a Novell network, XP is Professional Version 2002, SP2, and I am connecting to an HP9000/879/K260 running HP-UX 11i Ver 1 Release B.11.11.
Good luck and hope this helps...
