Why dos my VI pause? And have a red

[col_caf]

Hi,

Im relatively new to labview (8.0) ...  And my communications sub VI is acting funny at the moment.

The sub VI executes correctly, but it has a red boarder around (it's block diagram).  When the VI has fully executed my program pauses and the boarder flashes red to blue.  When I unpause it the program continues as normal.

I have not added a breakpoint, and I cannot think of what else may be causing it.

If anyone has any ideas I would be in your debt!!

Thanks a mil

It seems that you have unadvertently set a breakpoint on the block diagram (it is rather common when clicking above a threshold frequency ). Simply remove it by clicking on the b.d, with the breakpoint tool.

I dont think so...

Thats wat i thought initially so I went >

> Operate

                  > Breakpoints

And set search scope to "All VIs in this application instance", I also searched but the sub VI and the Top Level VI separately.

The search returns no breakpoints, so ive ruled that out.

Any other ideas???...

This behavior is exaclty the same of a block diagram breakpoint, so if you are sure that none was set, the vi may be somewhat corrupted.
Try to unblock the situation by setting/unsetting yourself a breakpoint (every time saving the vi and re-opening), or saving for version 7.1 and re-opening, or copying all the block diagram to a new vi (if possible).
