Skeleton compatibility and alt+tab issues

Hello.
First, OR have modefed skeleton.nif file. Does it mean, that i not need to instal skeleton mods like Coronerras Maximum Compatibility Skeletons  or Universal Skeleton Nif. By the way OR have conflict with Universal Skeleton Nif, look at picture. Should i instal any fix for that, or use OR skeleton.nif file, or instal other skeleton mod ?
Second, I can not retern to game after alt tab. Only black screen. How to fix it ?

Only use one skeleton.nif. The implemented skeleton shipped with OR is fine in almost any cases. Works pretty well especially with OCO (as I assume that you're using this judging from you screenshot).

In concern of Alt-Tabbing I'm not quite sure, but there was a fix for that already implemented in OR (the culprit may be full-screen or windowed mode). You may also try Oblivion Display Tweaks on Nexus, there's also a Alt-Tab-fix for full-screen mode.

You dont need any skeleton. The skeleton shipped with OR is compatible with all mods (it is the coronerra's one).

You cannot alt-tab in full screen in directx. Set bfullscreen to 0 in Oblivion.ini.

@Alenet
What happened to the fake fullscreen feature of the OR? Is it still coded in? The OP wouldn't have the alt-tab issue then...

It is but you have to set up bfullscreen to 0 in oblivion.ini.

Gotcha, gotcha. Cool.
