skirting tool

Updated to the latest versions of Sketchup and PlusSpec this afternoon however when using the floor with skirting, it doesn’t cut the skirting as I go past a door. I’m tapping command on iMac.
Am I doing something wrong or is there an issue with the latest software? I haven’t used skirting with the floor tool much so am I missing something? Worked fine last week.

Ok just worked it out, I wasn’t tapping the ‘option’ key. LMFAO!
