Hi all, I have the CanoScan LiDE 700F scanner, using MP Navigator EX v.2.1.4 on OS X Yosemite 10.10.3. After scanning the first page, using MP Navigator EX v.2.1.4, I am faced with a dialog box asking me whether I wish to scan another page. I adjust the scan face and click 'Scan'. However, after this, the MP Navigator EX v.2.1.4 displays a dialog box saying 'Searching for scanners'. After showing this for about one minute, I am compelled to Force Quit the MP Navigator EX v.2.1.4 software, since it has stopped responding now. I have reinstalled the software in an attempt to solve the problem. The USB cable being used is the one included by Canon in the box of the CanoScan LiDE 700F. The cable is not the problem, because the scanner manages to scan the first page wonderfully, but stalls on subsequent pages. Please help me. Thank you very much!
