R532 contextual menu in compresed (remote) files can fail

[dwaltz]

While operating on the content of a compressed file, if I right-click with the mouse on a file in the archive, the program sometimes does not show up the contexual menu and after a short while a pop-up window shows up with title "FcContextMenu64" stating: "This program is used internally by FreeCommander".
The error seems to be triggered from opening large zip files on a network disk, so might depend on the slow trasfer rate respect to opening a local file.
