I was having problems with Designer 1.187 crashing repeatably everytime I manipulated a pattern of a Oak Leaf I created. This was driving me crazy until I discovered the .ptn file was over 4 M . I then opened the .ptn file in Pattern Editor and went to Edit > Pattern Settings and discovered the Oak Leaf was 60" x 35" I then changed the pattern to 5 x 3 and no more crashes. Aparently I had scanned the leaf at a high resolution and when I brought it into Designer it took the high resolution image and made it into a huge pattern.
