Keyboard layout changes itselt while playing

[dvdmcwilliams]

Well my problem is the following, i play in a few legend servers and all gives me the same problem, i use a spain spanish keyboard (not the latin american one), a few minutes (could be 5, 15, or half hour) after playing, the layout of my keyboard changes from spanish to US english, i mean if for example my interrogation key in my spanish keyboard is just 2 keys left from backspace, it changes to the one next to right shift as in the US layout, could this be a tekkit legends bug, or what could it be?, i found this really annoying, because i got to touch every each key to find the right one, plz i need someone to help me solve this problem, thanks in advance!!
