Hi Sizo Ndlovu,
Unfortunately I don't think there are any other alternatives currently. Please refer to Bill's response in the thread - ATE Rendering Issues Agentry 6.1.0.3
My understanding is SAP are working on a new rendering engine for ATE that is compatiable with newer platforms like iOS / Android / WPF. Hopefully that isn't too far off because it will be a big help in speeding up the development workflow 
Cheers,
Stephen
