I have a Sony Artisan Monitor which I am nursing along as long as it holds up. The only problem is, when it comes time (every 30 days) to recalibrate, the spider doesn't stick to the monitor screen. I have tried cleaning the monitor glass and moistening the suction cups on the spider. No go. I end up holding the spider against the monitor while calibration takes place. Not the end of the world, certainly, but inconvenient. Any suggestions?
