My front panel is causing my vi to run at the wrong frequency.

My vi worked fine before I made my front panel into a useful GUI. The code was not changed only decorations, colors and position was changed. Now my vi will not operate at the correct frequency. I know this because I should be sending out a bit pattern at 25Hz and the oscope shows a change with the new vi. If I reduce this vi to 1/2 screen and the view the top of the front panel the vi runs fine as soon as I view the lower part of the front panel or go to full screen the frequency is wrong. I also found that by deleting two large decorative boxes the vi ran fine. I have played with the graphics settings and the only thing that helps is setting the resolution to 848x480 then the vi runs fine but looks funny.
Any suggestions? Windows 2000 with LabView 6.1.

Sounds like you are low on memory or CPU.

Make sure you display is set for 16-bit color.

Make sure none of the indicators are over-lapping.

Hello;

That is definitely a memory issue. The first and easy choice is to upgrade the ammount of RAM you have on your machine.
You can also change the front panel so you can reduce the memory overhead created by it.

Filipe,

Thank you for the input but this is not a memory issue. My total system memory use with the vi running is a maximum of 120 MB out of a possible 512 MB.

Ben,
The CPU usage is about 85-95% with the vi running. I already tried setting the color to 16-bit but it had little or no effect on performance. I'll have to check on the over-lapping indicators.

Thank you,
Mike
