Since being a Corel user from early on - I can honestly say that it DOES have glitches here and there. The best solution we have ever found is to load/install Corel BEFORE everything else. We do this anytime a software package acts up. Eventually you end up with a specific order of installation.
Unforunately, although often denied, the more software on a machine, the greater the possibility of crashes. The blame, IMO, is 50/50 - between the manufacturers and Microsoft - AND is one of the strongest traits of Macs, as claimed by their owners.
