I have a strange thing occuring on my laptop computer. For some reason, anytime i try to open a window that is meant to be activated from a jscript, such as a popup or from a drop down menu, the window may apear for a split second but then it is gone and will not remain open. can i have some insight into this as to what type of repair needs to be done to my computer, thanks. It only happens on my laptop. everything works fine on the other computers.
