    Default 1)Grid header often disappear when clicking other tab.2)Small square appear in grid

    - Sencha Ver. : Ext JS 4.2

    - IE : IE11, IE9

    =============================================================
    -Issue 1 : Grid header often disappear when clicking the other tab.
    What's the solution?

    - You can reproduce with following step.
    1. Click a left-menu "A". The A tab is created and there is a grid in the tab.
    2. Click a left-menu "B". The B tab is created and there is a grid in the tab.
    3. As soon as pressing the "SEARCH" button in "A" Tab, click "B" tab.
    ( Before data of "A" tab is loaded completely in the grid, you have to click "B" tab.)
    4. After 3 seconds(=after all is loaded in the grid of "A" tab), Click "A" tab.
    ==> The header of grid in "A" tab disappear!!!
    5. The issue always doesn't occurs.
    IF there are many tabs, the issue almost always occurs.
    IF there are two tabs, the issue sometimes occurs.
    6. Sometimes, even when clicking "B" tab after the load completely in "A" tab, the issue occurs, as well as before the load like step 3.

    I haven't heard of this issue. Are you able to recreate it in a test case?
