GUI freeze on duel core

I'm running Labwindow/CVI 8.01 on a intel duel core centrino duo. After running a small project with a break point, the gui hangs prior to termination of the code. This normally lasts for about 30 seconds before control is returned. Once it is returned, another application is selected as the current app and not labwindows itself. Using task-manager, only 1 core was allocated to labwindows with no effect. Disabling the core within the bios corrected the issue.
 
Does anyone know of a way to prevent this issue while running the full 2 processor cores?

Hi Atroyd,

 

This is a known issue and R&D is currently working on it.    There is a corrective action report taken, and your details have being added to it so as soon as there is a fix you will be notified.

 

Sorry for any inconvenience caused.

Hi Atroyd,

 

To assist R&D further on this issue, I was wondering if you could supply me with some example code and detailed steps which may help us further with this issue.

 

Any information you can give us which will help reproduce the issue would be great.

 

Regards,

We tested the problem using a new project containing the following code. If we ran without a break point, the system returned as normal. Adding a breakpoint into the second function and pressing "Go" once it was reach, would hang the system for the 30 seconds with the mouse changed into a hour-glass. When control did return, a different application would be brought forward as the current app.
 
Interface.c
int main(int argc, char*argv[])
{
  RunAllTest();
}
 
ToolTestList.c
int RunAllTests(void)
{
  return 0;   // Break point here
}

Hello

I tried to reproduce this on a clean machine (core 2 duo) with CVI 8.0.1, but was unable to. Do you have any other software installed on the system? I tried this with the user interface shipping examples and everything seems to work ok.

Thanks

Borland C++Builder 6 installed but it was not given control of the debugging enviroment. Other general packages include Sophos Anti-Virus, Microsoft Office and some of the standard Dell network support as offered on new laptops.

I dont have a core 2 duo laptop to test this out on, but I'm assuming if there was a problem with cvi and debugging on multi-core systems, it would have shown up in the tests i ran. I ran this on a desktop.

Can you try disabling the anti-virus services and see if it still happens.?
