After installing AcuCobol V184.108.40.206 on Windows 8 and using AcuBench within the project you cannot change values in the Property Window. Every entry (Values/Items/Events) is grey.
This is fixed in V9.2 and cannot be patched into previous products.
A simple workaround is to right-click AcuBench.exe, select Properties, select the Compatibility tab, and check the “Run this program in compatibility mode for:” checkbox. Once checked, the dropdown is enabled, and you can select Windows 7. Once you do that, AcuBench runs just fine.
