After 9.3.3 update, Acrobat crashes when debugging from JS console: when inspecting local or global variables. Error in module escript.api. System is Windows XP sp3.
I start Acrobat, check "Debug from start", type alert("test") in console, hit Enter and -- see above. Today I specifically found an installation with 9.3.2 and confirmed -- no error before update, and an error immediately after.
