Cannot operate of Flash on Browser after changing its zoom ratio

[dk64628683]

When the user operates the screen of a
Flash application on the Internet Explorer after setting its zoom ratio to a
value smaller than 100%, the Button object (mx.controls.Button) becomes unable
to click.

If the zoom ratio is changed to a
smaller value, the clickable area of the Button decreases from the lower-right
corner.

It seems to be possible to avoid this
problem by setting wmode to "window", but this value needs to be
"transparent" for other functions to work.

Please inform us how to fix the problem without
changing wmode.

The conditions of the problem are as follows:

  - OS: Windows 7 Professional SP1

  - Browser: IE11

      Version: 11.0.9600.17633

      Update version: 11.0.16(KB3021952)

  - wmode: transparent
