mes in exe - separate thread

[ssimop]

The following "Main" function calls and runs function in separate thread "Function_Thread" with no problem.

Function Main

Code:

Copy      Help

str text="test"
mac "Function_Thread" "" text

Function Function_Thread

Code:

Copy      Help

function str'text
mes text "Label"
ret

However, if "Main" is converted to exe directive "mes" is not run in separate thread "Function_Thread".

Any advice is mostly welcome.
