Lost hotkey for swithing from ASP.Net aspx to source

Hi

I am an old user of Resharper and sometimes it happens that a keyboard hotkey is lost. I normally solve this by swithcing to Resharper 2.x mapping and back to Visual studio mappings.

This also worked this time (lost Shift+Alt+L - Locate in Solution Explorer) but now I cannot switch from ASPX view to ASP.NET code behind file using F7.

Is this a known issue?
