processor use when minimize window

[Aurelien75]

Hi,

In my application, i have a very strange behaviour.

My program takes about 4% of the processor, all the time but when I minimize the window of my application (in .exe, not in labview), my program will take 100% of the processor for some minutes (about 3-5) and freeze all the program (even the task manager).

This behaviour arrive only is my program was allready running maximised for some minutes (30 minutes at least).

Is anyone have an idea of what labview do when minimizing a programm ? or what can i do to avoid this kind of behaviour ?

thanks...

You will need to provide some more information. What is your program doing? What is on the front panel? Is it just CPU usage, or do you see an effect on memory usage as well?

There are no effect on memory load, just on processor use.

My programm reads about 100 shared variable, saves them into an access database and display graph on front panel.

Hi,

It's an issue about waveform chart and autoscaling. You need to turn off autoscaling and every will be OK.
