If I add LazBarCodes I still don't get the crash, even if I do a clearn rebuild of the IDE...
JD, could you add Images4Lazarus and LazBarCodes again and see if the issue comes back? Then remove only Images4Lazarus, rebuild, add Images4Lazarus again, rebuild, remove LazBarcodes and rebuild again. If the bug is in LazBarcodes I feel guilty and want to fix it.
