I have been using ReSharper for some time and since I can remember every time I install Resharper, it's default keyboard shortcuts override Visual Studio's CTRL + F and CTRL + SHIFT + F for "Find" and "File in Files". It happend with R#3, 4, 5 in VS 2005, 2008 and 2010.
I don't have any ideas why would that be a good idea, but if this would bug it would be fixed by now.
Does this even happen to others? I checked around our company and I'm not alone.
No, never happened to me (I'm using Resharper 5).
If you check resharper's keymaps, you'll ctrl+f is not listed.
I've been using ReSharper since v2.5, and this never happened to me as well. Perhaps sometime ago the keys got mixed up. Try to reset your key bindings to default, and after that apply one of the ReSharper key schemes (VS or IDEA).
If this still happens, check maybe if your keyboard layout is that of US, or maybe something else...
Yep, this has just happened to me after a reinstall. I was using Vs2k8. Realised I didn't have resharper 4.5 installed. Closed VS, ran install, selected the same settings as I had been using for the last 8 months (VS settings) and then restarted VS. Now no ctrl+f or ctrl+shift+f! Very odd.
UPDATE: Well I found out what it was. The Find box had been relocated behind the Windows taskbar. I had to move the taskbar to the side of the screen, so that I could drag the find box back into the usable window space. No idea if this was a Resharper caused change but there was a direct correlation to the install.
