#80 REX client fails to start

[Tedd Hansen]

Computer configuration:
* Windows Vista Ultimate 64-bit English
* Clean of any virus/adware/etc
* Quad 2.4GHz CPU (Intel Core2 Quad Q6600)
* 8GB RAM
* Nvidia 9600 GSO with latest drivers

Error description:
REX client freezes with "Not responding" and black content in window when main window comes up. Before showing any login screen.
REX client uses exactly 25% CPU on a quad core system, indicating that it uses 100% CPU with a single thread (limited to 1 of 4 CPU's).

Steps to reproduce:
* Uninstall REX and ensure "C:\Program Files (x86)\RealXtend" is empty
* Delete "C:\Users\<username>\AppData\Roaming\realXtend\"
* Install latest REX viewer
* Start latest REX viewer from icon in start menu

Versions affected:
All versions except the initial release OpenSim developers received in Finland.

If you have any further questions or want me to test something please contact me. tedd@konge.net or Tedd1 on IRC.

Cheers,
Tedd

SachaMagne: even in fails in 0.3x client
SachaMagne: 88xx are ok
SachaMagne: in 78xx it crash on startup, not even starting drawing screen
SachaMagne: in 96xx we "catch" briefly an opengl error
Mutjake: Seems that GF 6150 is also affected, danx0r_ had similar problem too.
LasseO_lc: We're using Ogre 1.4.9 with modifications. I'd believe problems come mostly from switching between opengl contexts, even if both ogre itself & sl renderer itself should work. May be some nasty & strange optimizations in the drivers
LasseO_lc: basically, one should not write programs like rexviewer, that have two renderers
mikkopa: ogre.log is in the installation directory
SachaMagne: ogre.log doesn't exist
LasseO_lc: The logs are not always helpful, though.
LasseO_lc: Especially startup things
mikkopa: other logs are in C:\Users\username\AppData\Roaming\realXtend\logs
