I have been running Logos since before Logos 2.0 on various operating systems beginning with Win 95. It has NEVER crashed on me until I was forced to "upgrade" to 6 so that logos would continue to work. I have opened Logos less than 10 times since I installed 6, and it has crashed three three of those times while performing simple functions (clicking on words or highlighting them to copy). I figure that's somewhere between a 33-50% failure rate. This is unacceptable.
Logos threw the ball back in my court, I'm supposed to gather information to help them fix it. It looks like a time consuming process and I don't feel like this is my responsibility,
Logos 5 was slow to load up, but at least it worked consistently once it started.
