Loads a blue prism queue from outlook 2. Processes the queue by selecting the url in firefox and printing a page. My problem I load the queue and when I run the process by stepping through it in the process studio it works fine. When I run the second process from the control studio I get the following messages randomly. The action which errors out is a simple "Global Mouse Click Center" on a button. Exception at Stage  Print Page  Internal-Failed to perform step 1 in Navigate Stage 'Click Printer Icon' on page 'Print' - Unable to match any Active Accessibility elements to the supplied query terms - When I try to find it in the item that bombed in the application modeler I am able to spy the element. No sure what the problem is here. Appreciate any ideas to try.   Tue, 03 Jul 2018 01:36:00 GMT https://community.blueprism.com/t5/Product-Forum/Process-works-when-walking-through-it-in-the-process-studio-but/m-p/86057#M36970 CR 2018-07-03T01:36:00Z https://community.blueprism.com/t5/Product-Forum/Process-works-when-walking-through-it-in-the-process-studio-but/m-p/86058#M36971 Control room runs processes at a much faster speed, so any weakness in the synchronisation logic (ie wait stages) that was not apparent while running slowly in Studio is suddenly exposed.
