Labview problems, file corruptions, hang ups, etc..

Question

we are having endless and constant problems with labview.
The problems are all reproducable on 3 different machines.
Im going to list the 3 most troubling.
The biggest problem right now is that our vi files keep getting corrupted approximatly every hour of work. The files cannot be reopened.   Upon repopening the file, the processor utilizes 100% of the cpu.  The three comptuers are all checked out to be okay, hard disks, ram, etc, and one is ever brand new with 8gb or ram..  I suspect the problem has to do with the matlab script environment.  On one of the comptuers, after installing labview, i cant even get matlab to start up, it gets stuck utilizing 100%   of the processor. This is the latest and greatest edition of matlab and labview 8.2 but was 8.0 a week ago.  The reason we upgraded is to fix this. This is a huge disapointment and has costed many weeks of work.  We are now going to try to remake all teh sub vi and matlab script, again.  I feel the problem is the programming langugae at this point.
Another problem is that labview keeps hanging up when we are double click some of the graphical charts. It happens sometimes but not others but generally a few times a day..  Again, the problem is reproducable on all three computers. I think the problem has to do with the graphical objects being created by being copied rather then recreated each time from the front end but i dont  see why this would matter as they should not be inheriting any properties.
Each time we create a new graph or object on the back panel, it goes to some artibrray position on the front panel which seems to be a huge distance from the rest of the objects.  Moving these objects takes a great deal of time, around a minute each time,  there has to be a better way then recreating the object and duplicating its properties each time on the front panel.   No matter where we align the grid, the new objects go to some arbitrary position.
Just wondering if anyone has seen problems like this before....
I doubt is just us.

I have never seen this in many years of using LabVIEW, on multiple systems (desptops, laptops, even Dell's with Celeron processors ) Can you repeat this issue with a simple VI and post it here so others can test it?
"Another problem is that labview keeps hanging up when we are double click some of the graphical charts."
Do these charts contain large amounts of history data? Remember, if you are diplaying data in a chart, there is no need for it to contain 10,000 data points, as your screen is probably 1280 pixels across. Can you post a VI with one of these charts that gives you trouble?

I don't know if LabVIEW has a feature that lets you control where the next new object on the front panel will be placed, but I have found it MUCH easier to click in the general area on the Block Diagram where you will want the object, then go to the front panel, copy the control or indicator or chart, click in the general area on the Front Panel and paste your object. The control or indicator in the Block Diagram will be placed where you last clicked. That makes copying so much easier, since the object in the block diagram is so much smaller.
