I've just tried to do some pretty urgent testing with a borrowed dual Xeon workstation with XP on it (has 2 serial ports), in order to do some electrical/thermal work. We have a TC-08 and an ADC-16.
As on some other PCs, the software occasionally crashes with no error message and I have to enter all of the calculated parameters again from scratch. I've tried 5.13.7, 5.11.8, 5.12.4, 5.12.3, 5.12.6, you name it.
May I suggest an introduction of PicoLog version 6? Logging software should, above everything else, be reliable. As it stands it's useless, having this of whether or not it may or may not crash at any time depending unknown criteria.
We're looking at USB versions of the above but I'm afraid we'll be lumbered again with the infamous 5.xx.xx syndrome
