main program freeze when i change the position of the subVI`s front panel

[yehchia]

Hello everyone,

I have a main program that read DATA_1 from data socket continuously. In this main program, i call out a subVI through VI Reference. My problem is, when I move the front panel of the subVI around, my main program will be freeze. Then DATA_1 will show 0 Value altough my source data isnt 0.It happen only around less 1second and after that the value of DATA_1 will be back to my actual value.

It only happen when I move from 1 corner to another(bigger distance). When the distance is short, the main program doesnt hang. 

I tried changing the Window Behavior of the subVI. But it doesnt solve my problem.

The following is the  Window Appearance Setting for my subVI.

Anyone know how can I solve this problem?Thanks
