I can confirm all the three issues you mentioned appear for me as well on my laptop (Win 8.1 U1 x64, Chrome x64). With the third one, I actually went a step farther by creating an empty .xml file and selecting it with the Open dialog but then Pleco throws an error anyway. There is also the fourth issue, which is that the CPU usage is ~40% even when idle. Other than that, everything works flawlessly (to the extent that I tested it).One [...] there is no connection to the camera, [...] second [...] the touch screen, [...] third problem I've had is trying to backup flash card files. Instead of providing a "save file" window, it gives me a "open file" window that obviously then doesn't allow a backup file to be saved.
