Mark,
This is feedback about 2505.
I downloaded it today and installed build 2505 over 2500 on Win 8.1, but it wouldn't open, the splash screen just sat there for 10 minutes until I ended the task in task manager. I got this same result when trying to open an existing .nmf file. I rebooted and tried again and I had the same issues. Then I uninstalled, reinstalled, and retried, and again the splash screen just sits there, then I rebooted and it opened. . . shew!!
Now it was working on My Dell Optiplex 3010 PC.
Then I installed it on my Dell XPS 12 tablet running win 8.1 and this time I uninstalled build 2500 and installed 2505 from fresh. It hung up after install like above so I rebooted, and then it worked when trying to open an existing .nmf file.
Now it was working on two machines.
Then I went to a Dell Inspiron, of a co-worker, runnning Win 8.1 and installed build 2505 and he had never had any version of AGX on that machine. I had a similar experience with my tablet, except after the reboot it initially didn't work, and I tried to open the .nmf and it opened.
It installed fine on another PC with Win 7,
Just keeping you up-to-date I have it running on 4 machines now.
Best Regards,
John Nowlin
