Automatic Refresh in TiGL Viewer crashes for big files / slow file systems

[CLiersch]

If you have large CPACS files in combination with a slow file system, the automatic update of the TiGL Viewer sometimes crashes.
In these cases, it seems that saving the CPACS file (which takes some time) triggers the update method in the TiGL Viewer twice (you can see that the model is re-drawn twice, followed by a crash of the viewer). This behavior was seen using TiGL Viewer V3.2.3 on MS WIN 10 with a large CPACS file (approx. 50 MB) on a conventional HDD, being accessed by other software in parallel.

Proposed solution: Assure that the TiGl Viewer update method works properly if saving the CPACS file needs a significant amount time.
