I always recommend that my CAD users log off every night and preferrable reboot. When I get call about some function being flakey, the first thing I ask is when did you last reboot. Then I tell them to reboot and call me back if the problem is still there. I get very few call backs, like 1 in 100 calls.
If you run on Windows, memory leakage is still an issue, even with Win7-64.
While you may be something 'quirky' in NX8, yet it goes away after a reboot, then report it to GTAC so they can investigate it as it will be the only way it gets fixed in future builds.
When I first started investigating the use of Windows NT for UG V16, I had 3 PCs on loan from vendors for evaluation. All 3 systems showed a similar problem. HP sent a tech from Houston to PA to see for themselves what the problem may be. He was there a full day testing and trying different things. In the end, about 3 weeks later, they asked me to try a new graphics driver, which did cure the issue. At the next User Group meeting, HP acknowledge that they had found a bug with the help of a customer in ALL graphics drivers and had worked with the graphics card vendors to fix the problem.
Bottom line is that reporting problems does help everyone even though it may take some time to work through the issue.
