Wonderware Intouch Hiccup/stuttering

I'm hoping this is a fairly common problem that someone can answer quickly.

When testing an Intouch app with window viewer, I noticed that while watching the on screen clock increment every second, every 3 seconds the app seems to stutter or hiccup and skips a second, then repeats. This affects everything the app is doing, not just the time ie. while typing and watching trends.

I know that it's not my computers processor as I tried typing in notepad to see if the hiccup occurred with that too and it did not.

I also know that it's not a comms. issue as it did the same thing without any comms. The hiccup is exclusive to wonderware.

I hope this explains my problem pretty clearly.

It might also be a script you have set up to execute every 3 seconds. This action can occur if you invoke a windows function, like "PlaySound", etc.

When you find the script, you also have the option to run the script asynchronously... which will offload the burden on the single thread View.exe engine, and mitigate the stutter.

It's in there... review your scripts carefully.

Thanks! That was it. Now that I think of it, one of the scripts was playing a "beep" sound every three seconds and I remember just turning the speaker sound off, so it never occurred to me to check the scripts to remove it.

Thanks again!
