Sorry niner... Just did what your having problems with, works just fine. Actually, I bet I do that sequence of actions quite often.
More often than not, a lot of software problems are not always because of "bad" programming, but what I call a "dirty" system.
If your the type of user that likes to install all kinds of programs, uninstall them, reinstall others, play those stupid online game rooms that are filled with spyware and adware, installing chatware (the worst is aol), file sharing apps like kazaa etc., the kids surfing gods knows what sites and all their crap, and the list goes on and on...
and then still expect your computer to run flawlessly when you actually need to do some work, ha!
ALWAYS have a seperate workstation that is for doing work ONLY. I don't even get on the internet or install any applications on my workstations that are not directly related to my design and sign making.
All other programs and activities including client files, booking keeping, office suites, email, internet, etc., etc. all reside on other computers and my server. If something really starts going screwy on one of those machines, no big deal, any important info is always backed up to the server and I just format the HD and reinstall the OS.
I now I'm kind of ranting here, but I have have been using corel just as long as some and longer than others (at least since version 3) and I can say without a doubt that ver 12 is by far the most stable I have ever seen to date. I have ver 13 on the way and am told by many that is just as good if not better.
My primary workstation has been running, non-stop, since monday morning. and coreldraw has been running just as long and this weeks workload for corel has been pretty intense. No runs, drips or errors.
OK, I think I'm done now... The moral of the story is, if you don't have a dedicated workstation, get one, you'll probably find it will solve the majority of problems.
