LV "Not Responding" on startup

[seeker169]

I start up LabVIEW. A blank vi appears. I start programming.

Within 15-30 seconds, LV hangs and the title bar says "Not Responding". This lasts for approx 25 seconds. Then LV runs fine.

If my computer is not hooked up to a network, the "hanging" does not occur. The network I am on is not connected to the outside world.

I have LV 8.5 installed on a couple laptops and the behavior is the same on both.

This also happened on LV 8.2.  LV 7.1 did not have this problem.

Any ideas?

Source Code Control Provider probably? Try to turn off (if turned on) and see differences...

I'm having newbie user issues with this forum's interface.  It crashed last time I tried to send this message, so my apologies if it appears twice...

I checked on Source Code Control after reading some posts here.  I've never used it, so I didn't think that was the issues, but I'll try anything at this point.

I checked it by going to Tools -> Source Control -> Configure Source Control...

On that page in the "Source Control Provider Name" field was "<None>".  All other fields were grayed out.

I assume that means Source Code Control isn't the problem?  Or should I look for it somewhere else?

No, SCC is not an issue in your case... Try to rename LabVIEW.ini (located in the same directory as LabVIEW.exe) to LabVIEW.bak and start LabVIEW. Then new LabVIEW ini with default settings will be created and check if trouble still present Andrey.

Sorry, that didn't work.   It still hangs.   Tho I noticed I really do need to do a bit of housecleaning on my labview.ini file...

BTW, thanks for these suggestions.  As I said, I'm willing to try anything.

Hi Seeker 169,

Thanks for the post - and your interesting issue.

Does this happen straight after boot up i.e. rebot and then labview? OR is it after some length of use?

Is anything else running on these machine(s)?

Also what is the spec of your machine(s)?

Kind Regards,

James

I got a new laptop in yesterday and loaded LV on it (isn't that what everyone does as soon as they get a new computer? ).  Just for grins, before I loaded any of my source code on it I did some tests to see if LV would hang.

It worked just fine.

I've spent the morning incrementally adding my source code and various settings files I've tweaked over the years.  It took awhile, but I finally found the culprit:  buried in my 1200+ vi user.lib was a link to a vi that no longer existed.  I took that one link out and LV no longer hangs after startup.

Why disconnecting from the network changes the behavior, I can't say -- maybe LV is trying to search the web for the missing vi (even tho it pointed to my c: drive).  But whatever, it's all working fine, now.

Thanks again for all the help here; it helped me cross off some of the many possible problems.  And if I can figure out the "kudos" thing, I'll do that.

Thanks for letting us know.

I am aware I didn't help at all!

To rate the others - you just click on the golden stars.

Kind Regards,
James.

Hello,

I just want to add my experience and solution to LV2009 freeze, or hang, problem:

LV2009 "Getting started" window froze during loading of components. Nothing got better after 2 tries to repair my LV with the installation disk. After some headache, and after finding this thread, I recall that I had added window-shortcuts to other folders on my disk in the user.lib folder. This was done during my last working LV session. After removing the shortcuts LV started without problems.
