Metamorphose 2_0.7.1 beta, Windows 7 any version.
Right click "remove items(s)" doesn't work properly when removing multiple items. All but one file are removed. It works alright when removing 1 item.
Thanks for the bug report. I'm unable to duplicate right now, will look into this when a win7 system becomes available to me.
I can confirm the bug: Metamorphose 0.8.2 under Win XP SP3
