LoL's client is actively disturbing processes on my computer.

Since the last patch I've been experiencing extremely troublesome issues whenever the client is running. Simple tasks like opening a folder, saving an image or even starting a program don't get processed on multiple occasions while I'm logged in. There's also the issue of rightclicks (while browsing the shop or handling clubs) randomly crashing the client itself. Closing the client seems to return everything to normal, though.

As things are, League of Legends' client is literally boycotting my own operating system (Windows 7). You need to do do something about this. I can't be the only one having those issues, am I?
