I am migrating to FM Cloud. It seems that now FM16 will calculate all summaries on a Layout??? This is so annoying. I have summary fields off to the right that only calculated when user scrolled over, which has been very handy after finding a set of records. Now it's taking 40 min to calculate all fields upon opening. Pressing escape does not Cancel. Is there no way to Cancel a summarize???
I wish FM would stop breaking things!
I think you must have something else going on there. I have noticed no difference in FM16 from earlier versions when it comes to summary fields or calculations.
In FM 16, you can place the summary fields on a card window and let the user click a button to see the summary information of the found set.
This alleviates any problem of summary fields calculating since they're not on the layout a user goes to. They'd specifically have to click a button to see the summary.
Alternatively you could try a popover. I think those fields aren't rendered/calculated until open.
Another option is as philmodjunk stated, though I think a SLIDE panel is an object that doesn't render /calculate its fields until the active one.
I think I've seen this behavior for many versions as well: fields on the layout are calculated.
Try putting them in a tab or slide control panel that is not the front panel and see if that makes any difference.
