Hi Visakh16, I think your suggestion was the solution. But I found online that for modern browser, hiding URL is no longer doable (blocked by browser). And some said that using the javascript method could work only if the pop up
is open in a new window. The pop up behaviour is different from browser/PC setup. In my PC, the IE is set to open pop up in new tab, which is the same for the other PCs in my company, which I could not simply change it because some other in-house programs
need that setting...anyway, thanks for point out the direction. It really helps me to understand more in the problem that I am facing.
best regards.
