you are opening a fullscreen webview in your app then closing it?
please outline the steps you are taking and the functions you are using.
If you look at the demo included, there are several rooms, in each room a webview is created or resized and then a url loaded. so it is possible to have a webview and go to different rooms. note the webview will still be open so before you exit and room hide or destroy the webview
Set as 0 for default scales or a value greater than 0 as a percentage. This sets the initial scale/zoom of the website in webview. It must be set AFTER WebView_Init() and BEFORE WebView_Create()
Eenter a value from 0.01 to 100 to zoom in / out by that amount
