- Bug Fix: Moving apex then base on gated params page could causes screen repaints to leave artifacts behind.
- Bug Fix: If default set to alternate view, and the alternate view does not have both stress & rest series, but the non-alternate view does have both stress & rest series, and we are loading a review file, then prevent Toolbox from crashing (getting a null exception).
- Bug Fix: Starting transmission or planar animations would enable the filtering drop-down that only has context for short axis.
