v1.2: Shift+Alt+[arrow] doubles note-length?

Hi there,
I’ve just installed the 1.2 update and Shift+Alt+[arrow keys] won’t lengthen/shorten notes according to the grid value (as they used to), but they double/halven the note-length. Is anybody else experiencing this change in shortcut behavior?

Please see here.

Thanks for the hint! Case closed.

Same case with me, but Daniel’s advice is working. Thanks
