we have issue at our worklfow application running on Pega 7.1.9.
When users fill field "Quantity or Unit price" and then directly press calendar chooser Pega run sequenc to recalculate numbers at "quantity/unite price" and calendar is unavailable because Pega think he dont know that numbers (they are still filled).
So user must click somewhere else at page even blank space enought to save those numbers and after that he is able to use calendar choser.
The point is we have this problem only at Internet Explorer 11 if we are using Google Chrome everythings working properly thats mean:
Chrome: User fill up fields >click calendar >enter requested date.
