computer frozen in secondary thread

[RobertoBozzolo]

I have tested it in my home computer (Win2k SP4 - CVI 7.1.1 and CVI 6.0): it runs correctly in both environments withput even errors when stopping threads.

It seems that there is something damaged in your system: you could either reinstall CVI in your pc or try installing cvi to a different machine and testing this code there (this software can rn in demo mode of CVI, you don't need to activate that copy...)

Is that a compatibility issue? I have a same frozen problem when I run any CVI userinterface executable on one kind of embedded single board computer (SBC). The same executable runs perfectly on another kind of SBC. Anyone can explain?

Any problem with RunUserInterface()?

I am not sure about that. I can not even run Fmt () function. It seems to me Fmt () can not run correctly in multithreading. I believe something is wrong for CVI multithreading for those functions: timer (), delay (), fmt ();
