CorelDRAW 12 is a pig.
I have seen and duplicated at will those irritating Corel A.R.M. issues on a variety of Windows 2000 and XP-based machines. Considering the number of machines I have tried, I really have to wonder about claims from others stating, "My Corel 12 installation is rock solid."
One way I'm always able to make CorelDRAW 12 fail is by simply nudging objects around using the arrow keys. If I nudge one too many times, or simply hold down an arrow key to continuously nudge the Corel A.R.M. screen will always appear. Once that stupid A.R.M. notice starts appearing, it will always pop up and keep popping up and popping up again and again and again -even when CorelDRAW 12 is closed down completely- until you fully reboot the computer system.
CorelDRAW 12 has a number of other aggravations. I hate not having the "one shot" zoom tool from CorelDRAW 9. It's bad enough that, to this day, Corel has never properly adopted the extremely superior Ctrl-Alt-Spacebar keyboard shortcut system for toggling on zooming and hand panning functions used by apps like Photoshop, Freehand, Illustrator and a number of other professional level graphics applications. The one shot zoom tool at least made things somewhat tolerable. With CorelDRAW 12, you're stuck with a persistent zoom tool -which equals a lot more trips back and forth to a tool bar just to get some simple things accomplished.
I have a CorelDRAW X3 upgrade box sitting on the desk next to me. Later on I'll try that out to see if Corel has hopefully made some improvements -particularly in application stability. I have been seriously disappointed with Corel in recent years. If they can't get their act together, Adobe is eventually going to steamroll them right out of the marketplace. Illustrator has to add only a couple more tools for me to ditch Corel completely.
