Hello sgundappa,
Thank you for contacting National Instruments.
There are a wide variety of possible reasons for your problem. I am going to offer a few potential solutions. First, make sure that the client is running the correct LabVIEW Run-Time Engine. Second, we actually recommend using Netscape 4.7 or later or Internet Explorer 5.5 Service Pack 2 or later when viewing and controlling front panels in a Web browser.
Also, because of the constraints of a Web browser, user interface applications that attempt to manipulate the dimensions and location of a front panel do not always work properly when the front panel is displayed as part of a Web page. Avoid applications of this nature for use in a Web browser, especially those that present dialog box
es and subVI windows.
Furthermore, avoid exporting data-intensive VIs, such as those that have several charts or While Loops without wait functions. These VIs limit background tasks from performing in a reasonable amount of time, making front panels unresponsive when viewed or controlled remotely.
I hope this helps resolve your problem. If not, try creating a simplified version of your application and see if that also freezes.
