My VB6/Vc++ application uses the built in timer object. The VB app communicates back and forth with the C++ app at specific times. This was not an issue with previous versions of Windows, with migration to Win7 now it seems that the timing is no longer synchronized and the C++ process hangs up.
On previous versions of Windows I found that on multi-core or multi-processor computers I had to disable processors and cores until it looked like a single core, single processor computer. I think I got that accomplished on this Win7 machine, in task manager/Performance there is only one graph displayed for CPU usage. Previously there were 4. Is there a compatibility issue with the timer? and is there a fix???

Thank You.
