I recently upgraded to Maple 12 from Maple 11 and it seems that I have lost the ability to browse the contents of a matrix.  In Maple 11 I was able to right-click on the matrix block and use the context menu to open a tabular view of the data.  In Maple 12 I get a context menu with "Explore" as an option but it yeilds a dialog having a single button in it which also reads "Explore."   Clicking this closes the dialog.

Does Maple 12 have any capability for quickly browsing the contents of a Matrix?

When I right-click on a 387x387 Matrix my pointer turns into a processing indicator and the system sits endlessly.  Other than killing the maple server process is there a way I can instruct Maple to cancel processing and make it responsive again?

I have been using "Document Mode" in Maple 11 for the majority of my work.  I find that coding procedures and loops is stylistically different than the rest of my document content.  It is a bit uncomfortable using SHIFT+ENTER and struggling with manual indentation in the procedure and loop blocks.

What is the best editing mode for coding routines?
