At least I presume this will be an easy question, because I had no problem in the past doing this.
I now have Windows Media Classic v. 220.127.116.11. (rev 107). After WMC opens, let's say you want to play another WMC movie, The default setting forces the previous WMC window to close, replaced by the new movie. So there is only one WMC movie playing at one time.
How to get WMC movies to play simultaneously? I looked in "Options," and the solution is probably staring me in the face, but I couldn't spot where to make this switch - much as I had done so easily in the past. Would you please help me?
