Can not edit read-only files

Hi,

I am just evaluating resharper and I have an annoying problem:
When I open files which are read-only (in source control) ReSharper does not allow me to edit these files. Before I installed ReSharper I did not have this problem. I just had to confirm to remove the write protection before saving.

How can I recover this behavior with ReSharper?

TIA
Susanne
