I am facing problems with my Pre 3 (I know, I know, does not work yet, etc.. but I want to help).
I uninstalled Greg "old" plugin, luna restart, instaled the new one, luna restart, tryed to create an MSN (which I hope is MSN Messenger, as in Gregs old plug-in there were 2 different ones), I get a new card in which I can do nothing, on top left I can only read "libpurple Mess...", the scene is completely white with a black bar bottom.
Just a tip: there is a small HTML code line which you can use to solve this problem:
<meta name='viewport' content='height=device-height' >
I just do not remember in which HTL file you need to add it (I think it was in "main" - you will find info about it here in WebOsNation).
I am just very anxious trying this on my Pre3 and hopefuly contribute to it to better work.
