I have a strange problem which seems to have recently appeared. I used to be able to press the keyboard shortcut CTRL+M+O to 'collapse to definitions' in VS2010 when editing code, but it seems suddenly the CTRL+M key seems to have stopped working. When I now press the key combination I get the Open File dialogue.
I have tried the obvious things like resetting the keyboard scheme in Tools > Options but this has had no effect, I did also check that the default mapping for the keys were present and no other settings were overriding it in VS2010.
I have tried searching for an answer on the internet but can't find any other solutions. Has anyone heard of this happening before and do you know of a way to resolve this problem.
In addition, I very recently installed the new Windows Live Essentials 2011 suite, I am starting to wonder if this has any relation to this, although I'm not sure why it would! I have not had any of the apps running whilst VS2010 has been open. This could be of course a red herring!
Thanks
