22412) The RAM access log is limited to the 2MB
22513) In various occasions, global variables may be duplicated or without name in the DWARF information

22714) Source code disply only assembled code from vasm with option -dwarf
22815) After a new breakpoint set, the breakpoint list window is not refreshed
229-- User must perform an operation, such code tracing, to see the breakpoints list update
23016) Some ASCII characters may be not displayed correctly
e1f83a1a 231-- Probably depend how the text is displayed, this is related to the QT/HTML encoding done when reading DWARF file
24470541 23217) Potential legacy crash when leaving emulator in pause mode for a long period of time
e1f83a1a 233-- Need much investigation
235Cosmetic / UX issues
