I just upgraded to Corel PSP X2, and when I start it up got a bunch of dialogs complaining about duplicate image names related to the default brush, tube, and other files installed with the product. After some Googling and analysis, I found the filenames were stored with two cases for the drive letter, like “C:\Program Files” and “c:\Program Files” and PSP was being case sensitive in its dupe checking.
I decided to ignore the messages.
Today I was trying to create a custom brush from a selection and got the same messages. I happened to click on the File Locations button in the brush selection box, and there was under the Brush File FOlders list, two paths to the same location “C:\Program Files\Corel\Corel Paint Shop Pro Photo X2\Corel_01” and “c:\Program Files\Corel\Corel Paint Shop Pro Photo X2\Corel_01”. So the program loaded all the files from these locations, and did case-sensitive compare — and found duplicates! No way!
Remove the path. No more problems. Also work your way down the list and look for more duplicates.
