I can not preview high-res files in 4041, but on old version all works good
If you will reduce it to a half - it will allow to preview, but previes will be supr laggy. It is not good, because WM 4032 did allow me see maps up to 20 000 res. And only on this point it become laggy as 4041 that can not show me even 8 000 res without freezing
