When I press my combo box, my processor stops

[PauloM]

Hello,

I'm building my applications witch has a combo box to choose some timmings for choosing graph scales.
Sometimes, when I press this combo box, my processor load goes to zero and the rest of the application stops due to this.
If I restart my PC, this problem is solved... until the next time it happens - it can take days...

Has anyone experienced this?
Thanks,
Paulo

Could you post an example for us to look at. Thanks.

Here it is, sorry that it's big, I'm working on separating the acquisition from the interface to make it smaller.
But I'm affraid that you won't be able to see it, I just see it sometimes and then only some days latter it happens...
I realised that if I close LabVIEW it is solved - it's not needed to restart the PC.

Any comments on the code are appreciated.

Thanks,
Paulo
