File, Save: overwriting fails to truncate, on network drive

[mm0359]

Virtual PC 2004 SP1

Windows XP

avidemux_2.6.18_r170313_win32.exe
avidemux_2.6.19_r170410_win32.exe

1. Select a range, then Copy/Copy/TS to a Shared folder (+=- network drive).
2. Select a shorter range, then Copy/Copy/TS to the same file.
2r. Asks to overwrite, then saves as expected.
But file size is not reduced: existing extra data are left as is.

Ftr, overwriting to a local drive works fine.

This could be an issue related to Virtual PC, (though I don't think so after some basic tests).
Does anyone reproduce (or not) with a similar setup?

Hum, fwiw, I found
(VirtualBox) Cannot overwrite files in shared folders

if the new version is shorter, the tail of the old one remains.

Looks like it may just be something gone wrong with my Windows installation.
