Thank you Guenter, as you said, the problem maybe is not in the control, because after you told me nothing is wrong I used it in another computer and it works, the problem could be in the computer or in the labview, i'll reinstall and tell you what happens, tank you a lot
This is a known problem with LabVIEW 8.0 that I have run into many many times. LabVIEW 8.2 does not have this problem. The only solution is to redo the control and resave it. It also appears to be related to the specific installation. Here at JKI we've coined the phrase: "oh, you've got the d-bug... Good luck".
Thank´s Michael and all who helped me, instead of the LabVIEW 8.0 I gonna install the LabVIEW 8.2 but I haven´t the disk this moment, The next week i´ll tell you what happen, and it´s cool the phrase "oh, you've got the d-bug ....Good luck" I'll keep it in mind
If I recall properly, the "d-bug" is sometime tied to locked decorations or controls on the front panel. So, if the "d-bug" hapeens to you a lot, you might want to unlock these.
