May be a repost, but I couldn't find any info on using the inbuilt Web Browser effectively for the life of me.
I have found a way to load fresh web pages in RR. (You may have found like me that if you had 2 buttons that took you to different web pages, they didn't update properly.)
Firstly, edit the exit button on wbrowser.skin so that it reads: B10,710,0,90,85,"CLOSEWINDOW;Microsoft Internet Explorer||Exit","exit"
This will close IE every time you exit the skin.
Then edit the buttons loading your specific pages so they read like this: B05,[x],[y],[h],[v],"LOAD;WBrowser.skin;RUN;C:\Program Files\Internet Explorer\IExplore.exe|http://www.getmethere.co.uk/temp/trafficapp.html;Microsoft Internet Explorer;TRAFFIC"
I have uploaded the webplugin zip to my site as the one above was gone when i checked .... i had it working but i had a problem and managed to mess it up and eventually found it and with thanks to this site managed to get it working as i had it ....
It didnt have any details on how to get it working initially in the zip so i added in a quick readme but im not sure if its very accurate.
