Stellarium is strange

Something strange is going on. Chris responded and said that a value of 170 in his Stellarium version 0.12.0 on Windows Vista worked for him (with light speed on) using the test time-date of 22:28 EDT on April 15th. Not for me.

I tried Stellarium (same version) on the Horvatin's Windows 7 laptop. It was fine "out of the box." I looked at the SSYSTEM.INI file (at the path c:\users\heythatsme\AppData\Roaming\Stellarium\data) and discovered the value 315. I used 5 test events in 2013, all local daylight saving time, 24 hours (8 Apr 21:50, 15 Apr 22:40, 30 Apr 0:19, 16 May 23:30, and 31 May 1:09). I corroborated these dates in the Sky and Telescope web site against their printable list for April and all dates with the interactive tool, against McNish's interactive calculator, and against SkyTools 3 Pro. Both Sky 'n Tell and SkyTools were using the GRS longitude of 190. Presumably McNish is as well.

Could it be that Chris is editing the wrong INI? That seems unlikely. Could it be some "residue" from a previous version? We briefly touched upon that at our quick discussion at the DDO. Maybe he needs to wipe his configuration. Could his computer or Stellarium date, time, zone settings be different than mine?

On top of the differences Chris and I are experiencing, I'm not seeing any consistency between the other versions of Stellarium that I have... When I did not think there was any fundamental change in the application.

9: 140
11: 80   
12: 315

And I don't understand why now I need to use 80 in Stellarium 11 versus the 105 I arrived at earlier today?!

Go figure. Could it be the texture files are different?
