GoTo Layout script step slow
System: FileMaker Pro Advanced 12.0v5
OS X 10.10.3
I have a script which switches to a layout that has about 49,000. The table has some summary fields but they do not appear on the layout. When the script step GoTo Layout is executed, FileMaker says that it is "summarising " one of the summary fields which can take 10 secs. Why is that happening when the summary fields are not on the layout. If I switch to the layout manually i.e. not in a script step, Filemaker does not summarize the summary fields.
Is there a way I can stop FM summarising the fields during the script step as I want to speed up the script.
