"This is not the fault of mIRC, but rather how minimum/maximum window sizes work in Windows."
I likes mIRC too, but why always rejects the fault on the Windows API ?
the mIRC picture window client aera (Static), isn't a titlebar's window, it's a child window !
Since you can size a child window with 0 0 values, I'm afraid but it's not a windows api limitation.
I've fixed the bug by SetWindowPos() the Static child windows with good values.
Moreover, the window is hidden (-h switch, so at this point we don't care about titlebar or borders).
