Press Keys not working - numpad "',' vs "."

I attepmted a macro involving marker generation using the numberpad period shotcut, using press keys to record the key entries (I do realve there is a command already for creating memory locations). It never worked. I suspect it may have something to do with numpad comma beind returned when i press the pnumber pad decimal key. Not sure if this is a eurpean vs american keybaord translation thing, or if numpad comma is the correct entry. But it never worked....additionally, attempting to work with press keys froze soundflow a few times. Also, if the number of keys pressed exceeds a certain length, the entries disappear off-screen and there is no way to stop the rcord process because the stop button disappears.
