small text or similar over pointer?

Hi, I have recently found that what looks to be a very small section of text or similar (just looks like a squigle) follows the mouse pointer in Draftsight Pro. I see the mouse pointer and a small box at the end of the pointer and over this following the mouse is a squigle or small text. If I move the mouse the squigle moves with it before the pointer catches up. I have tried to take a screenshot of it but it doesn;t show which might mean it is something to do with the mouse or screen settings. It doesn't occur on any other programs, just Draftsight Pro. Has anybody seen anything like it before?
