LV 2009 SP1 corrupts front panel VI during 'save' operation

[barmaley]

My best guess is that corruption happens during 'save' operation.

Steps:

1. Slightly modify vi.

2. Run it, then stop and exit with saving of changes. (Saving takes unusual big amount time and cpu/memory resources)

3. Try to open vi and get the message "LabVIEW:Generic error... error code 3:Could not load front panel."

4. Exit from LabView

5. Start LabView and got the message "The last time you ran LabVIEW, an internal error or crash occurred at loaddata.cpp, line 3070"

Tried to reinstall LabView but it didn't help.

Any advice?

Thanks,

Boris

Can you post the VI so we can see if we can duplicate the problem?

[barmaley]

Sure. Please see attached.

Please post the un-corrupted version to see if the coruption is duplicated on other machine.

A corrupt VI is seldom useful since all it takes is a binary editor to corrupt a VI.

OK, Here it is.

Thanks.

There were a lot of things that you did not post so I skipped through them.

Did a diagram clean-up and saved without issue.

maybe you should duplicate what I did (load with sub-VI and X-Controls adn save) to see if it is still corrupted for you. If not start adding stuff back in until you find what causing the crash.

So no crash on my machine.

Ok, I'll try to do what you've suggested.

Thanks a lot.

It looks like rolling back to LabVIEW 8.6 solved the problem. Probably something bad happened during conversion of vi from 8.6 format to 9.0
