Hello, did a search here but could not find any threads related to this.
 
When I load up a project, the theme reverts back to Tungsten, if I have third party theme selected. So I have loaded up a third party theme, I save a project, exit Sonar, and run Sonar again. The theme is still loaded. When I open up a project, the theme reverts back to Tungsten. Anyone else experience this? Thanks!

The theme is saved with the lense.
So if you do not save the theme in the lense you will allways get back to tungsten when loading a project. Because at opening a project first the lense is called that brings up his own theme from the lense.
Load up your theme and then save them in the lense. Or go to the options of the lences and say that you do not want to save themes with the lenses.

Thank you, sir!
