i am gettign objheap.cpp error

[Gops]

i had a cluster ( pretty large one ), i added few more controls to the cluster. when i tried to open the main vi where this custer is a contol in the FP, further the cluster is used for processing(updating , reading etc)in the code.
When i try to open the main vi with the modified cluster i get objheap.cpp error and the labview closes by itself when i press ok. What could be the reason for this problem.

Is there any precaution i need ahere to when working with large clusters.

Did you get a line number? That would go a long way to finding the reason for the error.

I believe that your VI has become corrupted due to the number of controls on your front panel. Not counting the controls in the clusters, how many objects do you have?

The following link points to another link that discusses the interal errors of LabVIEW. It might help.

I also keep getting internal Labview fatal error in objheap.cpp line 592 (labview 7.0).
It started after I added couple of controls on the main.vi. Is there limitation on the number of controls on the Front panel ?

I am also getting this identical objheap.cpp error at the same line number 592. I was editing my VI yesterday on a computer using winXP operating system. Today, I am trying to bring it up on win2K OS and it will not even open due to this error!! I would like to send the code to NI but it has a lot of subVIs and since I cannot open it, I cannot get the heirarachy. I suppose I could send the directory(s) to them. Any advice is appreciated.

Sincerely,

Don
