Recommended Default for Alert Window
when Alert Window Causing Error

21:31 SloSto: that is the alert when first placed on chart

21:42 @Ensign-HA: ok, try this on your alert form

21:42 @Ensign-HA: first try to get Show Message box unchecked

21:42 @Ensign-HA: then try to uncheck the conditions boxes

21:43 @Ensign-HA: then change panel A to Always True and panel B to Always True

21:43 @Ensign-HA: uncheck Show True and Show False boxes

21:43 @Ensign-HA: then click Use as Default and close form

21:43 @Ensign-HA: so a simple do nothing alert property from is what you see when you apply one

21:43 @Ensign-HA: then build the alert up from there

21:44 @Ensign-HA: am thinking an alert form that does not have Show Message will help because it might be triggering show message when you start to edit form and change for the default the Sound to Silent too

21:45 SloSto: while you were away, I was experimenting and somehow the same alert was able to be placed without errors.

21:46 @Ensign-HA: still suggest you establish a safe and innocent default alert setting
