Packaged Tkx applications may experience failures on application exit
If your executables have problems on exit with messages similar to
Free to wrong pool aa1e78 not 89000000 during global destruction
despite no apparant use of threads in your application you may be able to fix this by forcing Cava to use the safe putenv option in the executable tab.
This issue is known to occur with the use of Tkx and Win32::OLE
