2.2 worked great but lacked some of the newer features, like copy and paste but it was extreamly reliable.
I upgraded to 3.5 it has just not worked out. It has proven to be untrustworthy. I have a lot of problems with polling. Items go down but the icons stay green. SNMP text is not updated on the icons. If an item goes down then gets acknowledged, it will go straight to acknowledged the next time it goes down.
I upgraded to the latest 4 beta and I find the same issues and now the executable function does not work.
One on the greatest things about the Dude is the ability to make your own external pollers.
Please let me know if it sounds like I just have something misconfigured. I have been using the Dude for years.
