Hello Slashupp,

Maybe you should try using 'PostCallback()'

1 - Use PostCallback( UpdateCB ) in the thread modifying the variables
2 - In the GUI thread, UpdateCB() will get called and will do the update work

Note : a mutex is still needed to protect the variable UNLESS these variables can be set/read atomically
