I ran into an issue yesterday in which I became unable to access the memory map tab in one of my views until I completely stopped debug execution (stop, not pause). This occurred when I tried accessing the first location in memory to view (0b000000). This generated an exception that a previous memory location did not exist and immediately sent control to the console tab in the same view. Clicking on the memory tab again would regenerate the exception immediately, preventing all access to the memory map feature until a complete halt of the debugging. This morning, I am able to access the location in the memory map that I had previously been unable to access, so the issue is clearly not always present.
