Yet more IDE woes

So today I am working in the designer on a windows form.  This form has over 100 controls (tabs with controls).  I am resizing a combobox when all of a sudden the IDE flips, flicks and bam, ALL of the controls on the form are gone!  I shut down the IDE, reopen, same thing.  I had to do an Undo Checkout to get the old form and lose all my work.

So, with the old form back, away I go.  I then right click on the same combobox, select Properties, and bam, the IDE just shuts down!

Please, please give us a better IDE for this beautiful Framework.
