I've got a problem that occured to me out of nowhere.
Today in the morning, as I logged in to my computer at work I cannot input Polish diacritical signs. For example rAlt + A should give Ą
but instead it gives no character. On the other hand : rAlt + rCrtl + A gives the expected Ą
sign. Also another weird thing: before the WindowsKey + R shortcut opened the Run command without any lag or nothing. Today it opens the menu at first, after that proceeds to Run command.
I've checked every possible language setting. Everything is fine. Keyboard layout - Polish (Programmer) also is fine. Checked my graphics driver (since they can have some issues with shortcuts) and nothing. The OS is malware free. Any possible issue with shortcuts checked with no result.
My computer: Samsung NP550P7C, Windows 8.1 Enterprise (after every possible update).
I hope there is another way than reinstalling the OS since I have alot of software to be reinstalled with it to enable me to work.
