Several Problems in Version 25.5.1

When i save the file and if the file already gives the message it slready exist and if i want to replace. If i select the option Okay to replace....it never gets saved until i try to save it the second time. 

Save As does not have Jpeg option

Slection pop keep comming in the working error and it annoying, can it not just open where it was last placed.

PS can be mush advance & user friendly
