I cannot confirm both crashes on EE 10.06 -> 11.03 x64, Vista X64.
Did you try to google for “Stackhash APPCRASH”? It seems like your problem isn’t EmEditor issue.
Trying to recreate “Crash type 2” … The macro didn’t seem to actually run.
This is normal, because the “Select…” command just “Sets the opened file as the current macro” (from the manual). This command should not run a macro.
