Blank bar across top of screen

I can't open that because LV 2013 is too new. Most people are just receiving LV2013 and haven't installed it yet.

If you could do a "Save for Previous", and save it back to LV 2012, more people would be able to look at this and help.

The problem does not happen in 2012.  It showed up when running a 2012 VI in LV2013.

Hi hartzde,

I was able to reproduce this with your VI in LabVIEW 2013. However, when I recreate this from scratch it does not reproduce. I added a raised decoration and set the VI size to be a fixed minimum size. I opened the 2012 VI in 2013 and it still did not reproduce. Are you able to consistently reproduce this with multiple VIs?

Did you resize to the same dimensions as the decoration?  If I don't have a window-filling object like a decoration, then I don't notice the gaps being bigger.

I have some apps where I have a full screen button for PASS or FAIL indications and i get the gaps.  It is not just with decorations, I just used that for the example.

I do see it all the time.  I have never not seen it.

I tested it again after resizing to the same dimensions as the object and I still can't reproduce it from scratch.

My steps were as follows:

1) Create a simple VI in 2012 with a while loop. (do you need to move it from 2012 to 2013 to recreate? or can you recreate with a new VI in 2013?)

2) Add a large decoration to the front panel

3) Resize the window so that the decoration covers the front panel

4) Fix the minimum panel size through the window size menu

5) Open the VI in 2013 and run it.

This did not reproduce the behavior. Also with your VI, I deleted the decoration and it still showed the behavior.

Did you do anything different?

I found it when I moved a program from LV2012SP1 to LV2013.  I recreated it wholly within LV2013.

2) Add a large decoration to the front panel

Yes, any object can be used that you can fill the dimensions of the screen.

3) Resize the window so that the decoration covers the front panel

Resizing the window affects the problem and resizing to the same as the decoration seems to be the most obvious, causing gaps at the top, bottom and right side.

4) Fix the minimum panel size through the window size menu

Right click the VI icon (top right) and Set the dimensions of the window to the same dimensions as the object/decoration.

I also set the run-time position to Centered and the Panel Size to the same dimensions.

I discovered today that if the position is set to Unchanged the problem does not show up. 

5) Open the VI in 2013 and run it.

This did not reproduce the behavior. Also with your VI, I deleted the decoration and it still showed the behavior.

Dang, this sounds A LOT like a post where they saw a "ghost" menu bar or something like that after upconverting like that.  I can't find the thread.  😞

I think they are slightly different manifestations of the same issue.  In one, a redraw occured and on the other it didn't.

[hartzde]

Adding an update:

After installing the new LV 2013f2, I see no change.  The gaps are still there.

Have you considered a complete reinstall of LabVIEW?
