"F5 Copy", "F6 Move" become disabled when selecting files

WinSCP 4.0.x, 4.1.x on Vista, Norton Commander interface.
When selecting (marking) files/directories with "Ins" or "+" keys, Copy (F5) and Move (F6) commands become disabled in the most cases. They get enabled only in the case when the last (very bottom) file/directory in the panel is selected.

Can you try that with 3.8.2?

Same problem with 3.8.2.
However, the problem only exists when running in Vista.
In Win2000, there is no problem (I tried WinSCP 3.8.2 and 4.0.7).

Few days ago, I have sent you a debug version of WinSCP. I guess you have not got it. Can you provide me a different address?

Martin,
I sent you another email address.
Thank you.
