VI execution speed depending on mouse movement

[Golzio]

Hi,
I have a large application that sometimes became very very slow. When It happens the only thing that I was able to notice is that moving mouse, execution speed of vi come back normal. I checked all the opened reference but I didn't find any not closed reference.
Any tip will be helpfull..

can you give us any other information or post an example of the program. Does it use an event structure, data acquisition, are you performing file i/o? If you can give us an example it would be most helpful. Thanks

It is very difficult post an example because the application is large and all the VIs running fast usually. There's no data acquisition and file I/O. The code comes from LabVIEW 5.1.1 and now is converted to LabVIEW 7.0. It doesn't use event structure for this reason. My application continuously read (from) and write (to) datas on LAN using VI server technology.
Unfortunately I only noticed that strange behaviour relative to mouse movement.

Thanks
