cannot resume a minimized vi

[hartzde]

LabVIEW 2012 f3

I have an application that works fine when first executed.  However, there are times when the application gets minimized that it cannot be resumed.  The circumstances are unknown and I have not been able to replicate the conditions.  The only solution has been to go into Task Manager and kill the application, then reopen it.  The program is installed on four PCs around our production floor and this problem occurs on all four PCs from time to time.  I know there isn't much to go on.  I just wanted to find out if anyone else has had similar problems.

Can you give a little more information about your issue?

Is this an executable? 

what version of LabVIEW was it written in?

what type of hardware is it interfacing with?

How big is the VI? ( Is it linked to lots of other VI's ?)

It is possible that with larger VI's you can run into problems similar to these where the computer lags when restoring it from a minimized window.

The program is an executable.

No hardware, just a program that takes barcode scanner inputs and checks them against data extracted from a csv spreadsheet file.

made up of a lot of sub-VIs, not very complex VIs

When you say it cannot be resumed do you mean the program actually freezes or simply that it cannot be restored from the taskbar?

[hartzde]

I cannot tell.  Nothing happens when you try to re-open the program.

The PC is fine and runs other programs, Word, email, etc.

I have seen applications frozen in the task bar before.  Its happens very infrequently and randomly in my experience with it.  I personally have seen Notes and Chrome do this.  Considering it spans applications it is my opinion it is OS related.  My guess is that when you click to restore there is an error but Windows thinks it succeeded and it gets stuck in a state where its not visible but the OS thinks it is.  If this is the same issue then perhaps you can try this and see if it works:  You can use Task Manager to maximize the window instead.  Even if the window is already in that state.  In the applications tab of Task Manager right click the task entry for the pop up menu.  The item for "switch to" might also work.
