Just curious. Anyone out there running Sentinel for the 536 on a Mac with Parallels. I am using Mac OS X 10.9 with Parallels 7, and forget about updating the scanners. It would seem the scanners do not like Windows running on Parallels. Using Windows 7. I program the scanners on a Windows machine with no problem. Haven't heard boo from Parallels people about this bug. Wondering if anyone else has problems, and if they did, how did they correct them. Thanks much!
