Version 184.108.40.206 is now available for download. It's got a series of small fixes and updates in it.
It turns out that you could resize the window to be too small. The next time you restarted, it would cause an error. (Thanks for the heads up, Ray!) It nudges window sizes back to something usable automatically now instead of causing an error. You can also turn off the bandwidth tests in case the routers in your path think the larger pings are a Denial of Service attack. Third, all ping data from the previous version is copied over to the new version so you don't start over on your graphs.
Each fix is a small thing that wouldn't be a big deal to most people, but I like to get the improvements out where people can make use of them. Let me know how you like it, and go here to purchase a full license after you've had a chance to evaluate it.
