That image definitely looks like an unstable interface to me.
Try setting Windows back to the default settings, and use the Import command again to see if the interface is still unstable (corrupt) or if it is repaired.
If it is repaired, then I would suspect one of the following:
1 - an incompatible WB skin
2 - you are running another customization program that is heavy on your resources, and the instability is being caused by lack of resources available to CorelDRAW.
3 - You have found a bug in WindowBlinds and/or it's compatibility with CorelDRAW.
BTW - I have had a couple of issues that invoke C.A.R.M. while working on a project in CorelDRAW 12, which seemed to occur when using multiple commands that required redrawing frequently.
Yes, I have the service pack installed (right after installing CD12 program and reboot).
The issue happened on my laptop, and I am assuming it was me applying too many commands in too short a time.
Running fine under "Luna" now.........yeah, I like luna - call me crazy.
I have also tested it with WB 4.6 (now installed due to liking some older skins that are not doing so well with WB 5), and running "5imple" for WB 4.
Haven't had a chance to push it under 4.6 yet though..........
Oh, forgot:
ATI Mobility Radeon X300 128 PCIe - Dell supplied drivers.
....like a fox.....
Now if they had made Luna customizable like 2000, but with more colors than 2 allowed, and customizable toolbar buttons.........
No wonder I bought Object Desktop.
I'll give it a shot.
