Environment

Vista Workstation 5.1.6

TGML graphics

Cause

Workstation crashes when the TGML graphic updates it's content. It's suspected that at the same time as the TGML graphic is updating it's content, the graphic is changed, which means that it's not there anymore to receive the updates.

Resolution

Change the registry key HKEY_LOCAL_MACHINE\SOFTWARE\TAC\TAC Vista Workstation\5.1.X\MaxTGMLFPS  (max TGML frames per second) to 0.
