User who are new to Finance&Operations, even used to Dynamics 365 Customer Engagement are a little bit frustrated because the busy-message "Please Wait. Processing your request" appears not so prominently on the middle upper part of the screen. So users click on an item on the bottom of the screen and do not see any response and the click again and again. There perception is: F&O does not react on every click only sometimes. It takes usually 2-3 weeks until they understand.

From a user experience point, it would be better to make this more prominent. From my point of view it does not matter, which way. Here are some suggestions:
* make the mouse pointer a sandglass/hourglass icon
* make the message appear in color and or maybe larger and or more in the middle of the screen.
* immediately grey out the contents of the current screen (with the message as it is)

Who else has this experience with new users?
