I had a budget report where I would typically drill down into the detail. It appears to be stuck in that drill down window as there is no way to back out of the drill down window (Back arrow is not highlighted to return to budget). The interesting thing is that the report no longer has the budget selection window as outlined below or in the customization screens. Is it possible by saving the report while in drill down I lost the budget connection? Corruption maybe? I don't see a way to get this back beyond recreating from a similar budget report or the budget window itself.
