LV2011 problem with several front panels

[shjukheter]

Hello,

             There is a bug in my software and I don't know it is common to every one or not. This not to be worry, I will notify you anyway. When I open only one front panel and one block diagram which having a program to communicate with a serial device. In this case, if I choose the VISA resource name, it obviously takes some time to popup the USB and after it show the port and front panel will stay in front you until you choose the device. Here, every thing is fine but when I open several front panels and working on only with serial program front panel to choose the serial device in VISA resource name. Then after some time, it took me to another front panel. I have seen this problem several times in past two months. More, even when I am decorating the front panel and front panel took some time after pushing some controls and switched another front panel.

Is this bug? Or I common for every one.

Using labVIEW 2011.

I'm sorry, but I did not undestand anything of what you said. You initially said you have a program that communicates with a serial device and you choose the VISA resource name and it "obviously takes some time to popup the USB." This is not obvious at all to me. What does the USB have to do with it? Even if you're using a USB->Serial converter, all that you'd see in MAX are the serial ports.

I have no idea what you are talking about with the multiple front panels and what "took you to another front panel". Are these VIs that are opened as a consequence of you pressing some button on the main VI?

Please explain more clearly.

I am certainly using labVIEW from two months. So, I did not use MAX in my past time. I only used one time to check my USB 6008 device but this is off topic here. I will tell you down here.

Suppose, If I open multiple VI's and I am only working with one VI that can communicate with my SERIAL device and the rest of the VI's(Block diagram and front panel) are rested. This case, if I click the drop downlist of "VISA resource name" of SERIAL VI, then it took some time(200ms or 100 ms, just it is a guess) to populate and it is switched to another front panel which were opened and rested before. Again, I need to come to my serial front panel again to select the COM port. This is one case.

If don't have any other VI's not opened than this serial Vi. Then it stays on the same front panel.

Is this bug came with labVIEW or  is it common?

This is a known issue with LabVIEW 2011 - the link gives some suggestions to 'work-around' the problem.
