Zip -- there is no conflict of drivers or between VS10 and 11. Many of us have both loaded on the same computer (so we can try to answer questions about various versions), and both work fine.
ironcutter -- I simply don't know what is causing this problem. I doubt that it is a bug as such, since a lot more people would probably be reporting the same thing. However, I acknowledge that a number of users have reported similar problems just over the past couple of months. I am starting to wonder if a recent Windows update may have started causing problems for certain users...
On thing you could try, if you haven't already, would be to go to the Microsoft DirectX website and download the latest update patch. The current one is dated November 2007 and can be found at
http://www.microsoft.com/downloads/deta ... laylang=en
Note that it updates both DirectX 9.0c (XP) and 10 (Vista). The number of your DirectX installation will not change, but the patch gives extra functionality in a number of areas and corrects other faults in VS11 in particular which do appear linked to Windows updates. Perhaps the 'building preview graph' may be one of them.
As for the release of the next version, I have no insider knowledge. None of us on this Board work for Corel -- we are all volunteers. However, the usual cycle is to release a new version every year around April. But I cannot say for certain that VS12 will come out then. A so-called new version -- version 11.5+ -- was only released in November. Whether Corel thinks that is enough for now, I don't know.
Certainly I am not aware of anyone on this Board being asked by Corel to be a beta tester for the new version, and I would have hoped that they would already be beta testing by now. Then again, they did not involve any of us users in beta testing VS11, and we all know the problems with the program revealed after it was released that might have been avoided with adequate beta testing by users beforehand...
