Re: please tell me why my customer form gets hung up
Thanks Yronium, for yer reply... sorry for not being clear or to the point with my post...
the problem that im having is that......the splash form after loading gets hung up....
notice that my splash form is the same member login form...that loads on during runtime....
the modules that i have used in my project are
1)modDisableLowLevelKeys
