Nova-T freezes on first load

[dgsmith]

Strange problem with Nova-T on one of our admin machines. The user logs in to SIMS as normal and clicks on Nova-T, which brings up the splash screen, but then it just "hangs", and requires a process terminiation to get rid of it.

 

Then strangely, with SIMS still running, if Nova-T is then reclicked to load it back up, it'll run just fine (no errors or logs stating the previous freeze or close). It has happened 3 days on the run now, so a bit concerned as to why it is doing this - it works fine once loaded too! It seems to be specific to 1 machine.
