[Bug 21966] Total Commander: Application freezes when queue-ing file copy operations

Still happens with wine-1.1.44, Ubuntu 10.04 64 (default window manager).

Regarding problem 1:
The window showing the queue of files to be copied is frozen only while copying
a file. When a file copy operation finishes, the window is updated (showing the
next file).

Regarding problem 2:
The main window is responsive once the current queued file is copied.

I blame the (system) function Total Commander is using to copy a file. It seems
it should be asynchronous, but instead it is blocking.

Any idea on how to find which function is used to copy files?
