In previous posts I described a problem I was having with 126.96.36.199 crashing XP Pro. I am using Bootcamp on a Mac Pro and have had no problems with 5.19.1 for Picoscope and Picolog in the past.
With both Picolog 5.19.1 and Picoscope 5.19.1 installed alone I don't have a problem. Picolog is the program I use primarily.
If I install in addition 188.8.131.52 for Picoscope, I get crashes and Picolog doesn't work properly. Having XP Pro remove 184.108.40.206 solves the problem. Is this a known bug in 220.127.116.11?
