I have had this issue ever since joining my current company. The Nimsoft IM just occasionally hangs for us. What happens for when things go bad is that, it goes into a busy, waiting, pending state b/c my mouse cursor changes from the regular pointer to the spinning waiting cursor. And when I'm using IM it will just go into that state and stay there for a period fo time.
Whenever this happens I usually have to jump onto eithe the Primary Hub, or one of our Sub-Hubs and cycle the UIM services.
I have an issue opened with Nimsoft regarding this but it goe Much much better after I upgrade to robot version 7.62 and hub version 7.61. We were previously using v7.05 and the difference was night and day.
