Tony, What you say is true, but the fact with many ham radio applications is that they were designed to run on Windows 3.1 or Windows 98, and have never been updated to run on later versions of Windows. WinXP *usually* supports those applications, but the game was changed with Vista and Win7. If the applications do not update to abide by the "rules" of those newer operating systems, problems such as this can occur.
Is this an OS problem? or is it an application problem? Sort of a "chicken and egg" answer. Business applications are quick to make the changes required to keep up with the OS requirements, but many ham radio applications are not upgraded - I guess the authors do not get enough support contributions to make it worth their effort to change things. This is one of the reasons I will stick with WinXP for as long as possible. I have a number of applications, including my preferred backup program that will not run on Vista of Win7. 73, Don W3FPR On 9/13/2011 7:46 PM, Tony Estep wrote: > On Tue, Sep 13, 2011 at 6:44 PM, Lyle Johnson<[email protected]> wrote: > >> ....Delayed Procedure Calls (DPCs) often produce huge latency spikes.... >> > ============= > To test for this problem on your system, download the DPC checker at: > http://www.thesycon.de/deu/latency_check.shtml > > Note that it takes a lot of latency to cause an audio problem.
