[9.0a 64bit] F6 + F2 : the source file doesn't disappear

[Ammammata]

W7 64bit
I often move files from the HDD to my USB pen, using F6 + F2 to queue the items, from left panel to the right one

Sometimes it happens that the source file remains in the left panel well after the move task has been completed: I can't delete it nor view, TC asks for administrator rights but it fails
Changing folder and going back to the source doesn't work
Even closing TC and returning to the source folder doesn't work
Then suddenly the file disappears

I'm sorry I can't reproduce this

It usually means that the file is open in some other program, like a virus scanner.

Sorry to hijack this. I try to post a topic, but every time I only get this error:

What do I need to do in order to be able to post? I made one post, and I've been here longer than a day.
Thanks!

since today it happened again and I'm using MSE, I added totalcmd64.exe to the "excluded processes" list

I'll report again if this doesn't work
