tool properties disappearing

Hi !
The tool properties window doesn’t appear when I 'm in the "hand-drawn animation mode, only in the default workspace. Is it normal ? It seems to me that it works before, but since I once closed the window toll properties It doesn’t work even if I do : “menu-windows-tool properties” Is there something to do ? Thank you for your help. ^-^

??? it’s some kind of magic !? However I did it several times before and it didn’t works. After your reply I’ve tried all the basics process … like menu “Windows” — “Restore default workspace” and … it works :-[ ::)thank you for … for … just thank you

I wonder if it’s hidden somewhere in your workspace. Do you have any of those little triangles that you can use to temporarily minimise a workspace? This might have been minimised.
