Hi, thanks for your reply.

But I got an error even if I do a trivial copy paste of your relevant part of code:

local function framehider(self)
    self:Hide();
end
 
... other code ...
 
TimeManagerClockButton:HookScript("OnShow", framehider);
TimeManagerClockButton:Hide();

But I always finish to get the error:

attempt to index global 'TimeManagerClockButton' (a nil value)

even if it works nicely if I load your addon ... so I surely miss something important here

Thanks so much for patience and help.
