Every time when I open a drawing in this program there are traces or trails behind the mouse and it is shifty or moving radically. I have uninstalled and re-installed the program in hopes to resolve this issue but had no luck. I could really use some help resolving these issues.
This happens because of the graphic acceleration. This could also be a bug in the application when you try to open a file with multiple items added. However, try changing resolutions because this simple fix works in many cases.
