Frame (Click)
From Mario Fan Games Galaxy Wiki
A Frame can reference many things within Click software, but it generally refers to the level or design area. Frame in this context was originally only used in Multimedia Fusion 1.5 (prior programs used level), The Games Factory 2 also uses this term.
Frames are generally only shown one at a time, but subapps allow multiple frames to run independently and simultaneously; this is useful for application development for things such as toolboxes and dialogs.
Other common meanings: animation frame and frame (a single screen update)
