LispWorks for Windows DLLs now run when the Data Execution Protection (DEP) is set at the highest level. The DEP feature was introduced in Windows XP sp2/Windows Server 2003 sp1.
DLLs built with LispWorks 5.0 and previous versions fail to run at this setting, requiring the application to be added to the list of allowed applications.
Note: LispWorks for Windows executables run regardless of the DEP setting.
