I've never had this problem before. It started yesterday. I can't use the Rectangle, Lasso or Ellipse select tools. I can select the tool. But when I try to hold down the left mouse button to drag a rectangle, lasso or ellipse, the selection lets go before I'm finished. I have PDN Version 3.5.10. I clear temp files on my laptop on a regular basis and do a restart almost every morning. I haven't installed any new software that might have affected PDN. I'm using the same antivirus program. I can't think of anything else that would interfere with the selection tools. Is it a PDN problem or something with my laptop? I can drag and drop files in other programs with no problem. ~ Eileen
