tool not shown with modifier ?

HI.
just upgraded from N8 to N10,
did not played with it much,but i have noticed,when have selection tool,and holding alt modifier key over event,the scissor tool is not shown, but it cuts the event and afterwards the scissors are shown for a short time… the same with selection tool to pen when drawing parts on empty area.
any one has that ?

today it works as expected,maybe needed PC restart :wink:
