I am refering to smart layout (single). Which accordning to documentation should readjust. 

• Fill (100% ) — To have the column widths on the user flow action form adjust to fractions of the total width of the user form or flow action form. For example, if you adjust the column on the rule form to be 25 percent of the total width, the column on the user form or flow action form will be 25 percent of the form width, and will grow or shrink if a user resizes the form.
• And on the skin I have following defination: 

Hi Afzal

Could you answer the below queries 

1) Can you share the document link where you found that smart layout readjusts

2) Can you share the screenshots of the following (this is to understand what is appearing on screen and what you are expecting)

    a) layout during window load

    b) layout after resizing the window(the erratic one)

     c) layout after window resize and then refresh(as per discussion this is what you are expecting)

     d) layout configuration

3) Is this issue happening only in IE. Can you check in chrome,firefox and confirm

Also let us know the PRPC version you are using.

Prpc version 7.1.9 , window7 & IE11.

Assume Blue box as IE11, and orange box as smart layout, 1 is during load, 2 at maxmize, and 3 resize to smaller size. 

Layout configuration.

Layout at refresh will go back to 1 in above diagram. 

Does this issue needs a SR? What I have observed is width is generated behind the scenes somehow, and it only gets updated at onload event not onchange event.
