Alt modifier issue

Hello,
I use SD to get the keys pressed by the user.
All works fine except for Alt+(i,j,k or l) !

In fact, I have this issue :
During all the operation I pressed Alt and don’t released it, then I
pressed ‘j’ (for example) two times. The first time the event correspond
to ‘Alt+j’ but the second time the event is only ‘j’. The same thing
appear with ‘Alt+k’ ‘Alt+l’ and ‘Alt+i’ but all is ok with over keys!

Thanks–
