There seems to be a compatability issue with the pattern editor software (latest version 1.17 and internet explorer 9. I have been using the latest version for a while now with no issues. Two days ago I installed IE9 and noticed that I had a problem.
When using "Export to image" it used to save the familiar grey scale image. Now it saves an image surrounded by a red border. I'm using an HP media center with phenom quad core processor 9500 and 3072 MB system memory. Nvidia geforce 8500gt graphics card and running vista premium home edition.
When I switched back to designer version 1.177 everything is fine again. Reloading V1.178 brings the problem back. Even after unistalling IE9 and going back to IE7.
EDIT: Unfortunately the forum changed the pics to jpg from png and added the black background on the first pic. It is really a transparent background. The background on the other pic is what the pattern editor software is doing.
