Thanks for the info! I followed your advice and cleared my cache, hoping that will solve the problem going forward!
Since I am working on a Mac I am usually using Safari but was advised that I should use Chrome when working in QBO.
I'll try to alternate between the two to see if I encounter any further problems working with one or the other.
Regarding the Add's I'll give the pop-up blocker a try, it's just a nuisance really since I am not used to this having worked on Desktop for Mac previously. It forces additional, unnecessary keystrokes and interrupts the flow of work.
