last time I used Mchesa it worked fine (about a year ago on a Win7 PC). Now, on a Win10 PC, I always get an error message from Java "com.sun.deploy.net.FailedDownloadException: Could not download ressource: http://popgen.net/soft/mcheza/code2/mcheza.jnlp" (followed by a list of "unknown sources) and "java.lang.SecurityException: illegal URL redirect at com.sun.deploy.net.HttpUtils.followRedirects(Unknown Source)" (plus more unknown sources). I tried to disable all Java safety measures and allow all exceptions (although "not recommended") - to no avail. I found an old Win7 and even WinXP PC - still the same problem. Seems really Java-related. Any idea on how to get Mcheza to work again? TIA!!!
