I am new to QBO having worked with desktop for Mac until recently. Finding that when I am working in QBO for a while certain functions are non responsive such as Sign Out and Help. Also, certain 'windows' that pop up on the home screen (whether I want the info or not) show empty squares with a message: "Something is not working right" when this happens. Meanwhile I am able to post new Bills, Deposits and Journal Entries - or so I think... Without having to re-check all the work I have done to make sure it actually posted, how can I be sure that that part of QBO is working properly when the rest is not?!? 

Very frustrating in addition to finding QBO very cumbersome and slow, loaded with Add's and QB trying to sell me more stuff I do not want nor need! Anybody having the same experience, any suggestions?
