Thanks for posting!
Would the zoom feature work for you? You can Zoom In by going to the View menu and selecting Zoom In or clicking third button from the left in the lower left hand corner. This would increase the size of all objects including the blinking cursor that's placed inside of an active field.
Thanks for your response, what you suggested works fine but as our layouts are virtually full we loose the full view on them .
Unfortunately, I don't see a better way to increase the size of the cursor. Perhaps you could include buttons on the layout to increase and decrease the zoom level so that users can easily zoom in and out when necessary.
