Timo,
There are two ways you can do this.
The first way is disabling tracing.
Execute->Disable Tracing.
When Tracing is in effect , the sequence editor or operator interface application displays each step as it executes.
This is useful when debugging but adds significant performance overhead to the execution of your test programs.
If you do not want to disable tracing for all the steps in your sequence file, you can disable tracing for a sequence call step.
1. Select the sequence file step and from its context menu click properties.
2. Go to the 'Run Options' tab.
3. Go to the 'Sequence Call Trace Setting'.
4.Select Disable Tracing in sequence.
Hope it helps.
Antonio Lie.
