Resharper removes VS2005 Shift+Tab keybinding

After installation of Resharper 2.5.2, my VS2005 has lost it's ShiftTab keybinding for "Edit.DecreaseLineIndent". Actually, Resharper even asks if I want to keep my VS2005 keybinding when I first used ShiftTab after installing Resharper, but even though I told Resharper to use the VS keybinding, Shift+Tab got lost.

I have found no way to restore this essential keybinding. I tried with VS Options -> Environment -> Keyboard, but this settings dialog of MS allows to change every keybinding except any keybindings with the tabulator key (because the focus jumps out of the shortcuts edit box whenever the tabulator key is pressed).

I also tried via resetting VS keybindings and also via resetting Resharper keybindings, but to no permanent solution apart that I had to re-enter my custom keybindings again and again...

Any solution to this problem? This is one of the keyboard shortcuts I use most often and not having it is quite annoying.

Thanks, Markus
