"unknown source position" threadid

[david_feo]

I'm using CVI 5.5.1 under W2k.
Applications using an external USB Driver DLL crash on ther end with an error Message:
Fatal Runtime Error
unknown source position thread id 0x72c
The program has caused a general protection fault at ...

Does anybody know how to prevent this?

We did not have that problem under W98 before with the same SW (different USB Lib)

Best regards

It sounds like it is a crash in the driver DLL which is why you don't have source. All you can do it work with the driver creator to try and debug the problem. Windows 2000 is a much different environment that would require a different driver architecture so their definately could be a bug in the W2K version of the driver.
