How To Change Input Language Setup

The problem is, when I've got one input language chosen and am working on a Word document, I am able to write using that language. As soon as I open other software (for example start searching the web), the input language changes automatically. This means I cannot write my document and then proceed using same language on the Internet, but I have to change the input language separately when I swap from Word to Internet browser.Is it possible to change the settings so that if I'd be using one input language in one software, after changing the software the input language would remain the same and not change? It is quite annoying, though it is probably helpful for those who are using different languages in different software and don't want to swap the language every time they move from one soft to another.Another annoying thing is that I cannot give the name to my file if there's a folder which has the same name. If I have folder 01 on my desktop and I have a file which I want to name as 01, as I press "Save" the file isn't being saved. Windows just opens the folder named 01 and shows it's content (in the same window where you need to enter the filename and have Save button). How can I change this setting so that Windows would let me save file 01 even though I've got folder with the same name.
