Hi Tom,
I have experienced this issue to and i am currently investigating this problem myself. For me the issue is the same as yours, Aware IM hangs at "Executing" and i have to restart the server to fix it. I think the cause is when trying to use document templates or functions related to Word on a server that has Office 2010 installed (have not tested this extensively though).
This is what i have noticed do far. First of all, i think this issue is related to Office 2010 and that there is something with the 2010 version that causes this issue. When this issue occur, "WINWORD.EXE" is taking almost 100% CPU on my VPS and it does not go away. I have even tried letting the "Executing" go on for quite a while but the issue does not resolve it self and "WINWORD.EXE" is constantly at the high CPU %.
Another thing. This issue only occur when i run Aware IM as a Windows service. When i deactivate the Aware IM as a service setup and run Aware IM with the standard configuration tool startup, i do not experience the same issue.
Here is how you can reproduce the error i´ve had (directed at support), at least this is an issue on my server and i think it is the same error as the one posted here by Tom. I noticed the error when trying to use the "Library" sample application and to reproduce try Aware IM on a WS2008 server (might be the same on pc) with Office 2010 installed and where Aware IM is run as a Windows service. Install and try to open up the "Library" sample application. When i try to do this, the first time i open up the application Aware IM tries to populate the application with sample data and here this issue occur. Aware IM hang ("Executing") and the data is not being installed and the above mentioned things happen with CPU etc.
Here is another post covering what i think is the same issue: Office 2010 and MS server 2008 problem>
Support, can you take a look at this or is there someone else who knows this issue/a solution for this?
Thanks, regards Henrik
