LabVIEW 2011 Block Diagram/Front Panel reacts slowly

[BMajor7]

Since today the block diagram as well as the Front Panel of my application (using LabVIEW 11.0) became very slow. Any modification (add item, move item, scroll etc.) takes more than a second. Restarting LabVIEW helps for some time and then it becomes slow again. Restarting the PC did not help either.

So, I tried to remove all items added today but the effect remains the same. When I try to close the Project Explorer LabVIEW does not react anymore (not responding). Very annoying.

I tried also modifying the settings of the graphics card: nope.

What do I do? Start the project again?

Any suggestions except not using LabVIEW for further projects?

Would be appreciated.

seems to be funny

Funny? No, not really. Believe me!

The LV 11.0 is causing me a lot of trouble. LV 10.0 was not that problematic. But I have a issue or crash nearly every day. Very funny if the file recovery does not appear afterwards...

I really regret the decision having used LabVIEW 11.0 for this project.

Best regards

No one?

I guessed so...:mansad:

some suggestions:

1.Using EXpress VIs and the  dynamic datatype may slow applications down.

2.Also placing graphics or control/indicators on top of each other,may force the front panel to be updated more often.

3.Another things that slow things down are graph or chart that contain a lot of data.

You please check all these,there are so many other reasons that make application very slow.So it would be better if you post your code.

Yes, I am familiar with these cases. But wouldn't the GUI then always be slow? As I said, the GUI works fine for some time but starts slowing down out of a sudden (at least no extraordinary interaction I might be aware of). I have removed all items that have been placed since this phenomenon occurred - it still happens! The only thing that works until now is restarting LV.

EDIT: the code is quite large and part of a project that is not supposed to become public. We have tried it on another company PC though and this issue did not appear there until now. I am using Win 7 and LV 11.0 SP 1, both 64 Bit using two monitors.

Some people have anecdotally mentioned that an "advanced heirarchy" (circular references) in classes has slowed down the IDE.

I've heard that NI will sign an NDA - then you can share your code with an apps engineer.

Computers don't run find and then start actine weird. There is probably something that has changed.

Could be you you have been filling the disk drive and now it is almost full or needs deframented.

The disk drive could be starting to fail (backup NOW).

A new anti-virus update may be cicumventing LV and slowing things down.

A new program may be running that is killing the CPU.

A virus may have been introduced killing CPU.

That is just my 2 cents,

You might try mass compiling your VIs. Since you mentioned crashes you could have a corrupted VI somewhere and the mass compile may clear it up. Do you have the separate compiled from source option set? If so, remove all of your cached comiled code and let LV create new object files.

Is your navigation window open?

If the navigation window is open, and your block diagram is very large, then it takes the PC a long time to redraw the navigation window whenever you start making changes to the block diagram such as dragging functions around.  Likewise if the the front panel is large when moving around FP objects.

If the nav. window is open, try closing it and see if things seem quicker.
