If you place the cursor over a block, MemoryScape opens a pop-up containing information about the block, Figure 61. The information in this window is, of course, specific to the block. For example, this pop-up shows that guard blocks were being used when the block was allocated.

When you select a block, MemoryScape highlights all other blocks that have the same backtrace. So, if 100 different blocks share the same backtrace—which means that the execution path within the program is the same, and they were allocated from the same place in your program—they’ll be highlighted. (Full details can be found in Task 8: "Obtaining Detailed Heap Information".)
