alt-grey * in the tree view pane expands all subfolders similar to what explorer does. The bug occurs when you do it more than once then the tree view duplicated the list of subfolders adding another one for each time you press alt-grey *. This seems to be visual bug only as refresh fixes it.
there is no such command as alt gray* in x2
what you see must be a peculiarity of the tree control
to expand branches the correct command is alt+right arrow, which doesn't play up like this
There might not be such a command as Alt-Grey* (or Alt-NumPad* as I prefer to call it) Nikos but it does expand the entire branch multiple times if you use it. Shift-NumPad* does the same. NumPad* gives the "Not applicable...." message.
Is this system dependent? I'm using Windows XP home.
