"Collapse Formula Bar" button is missing in Windows 7 default theme

Some Japanese LibreOffice users claim that “Collapse Formula Bar” button is missing in Windows 7 default theme.
This issue is caused with Windows 7 aero themes, Windows 7 basic theme. If we use a Windows Classic theme, it works fine.

It’s very easy to reproduce, but I couldn’t find the issue in fdo bugzilla.

Anyone knows about this issue? It’s a known bug already reported in fdo, an unknown problem with limited environment (such as Japanese Windows) or specification?

Reproduce step:

  1. Open Calc (4.0 or later; I tried with 4.3.0)
  2. Click expand button of formula bar (see below)
  3. There is no “Collapse Formula Bar” button, and we can’t collapse formula bar (see below).
  4. So we can’t collapse formula bar.

Please give me some information.

I see the same problem in my installation of version 4.2 and version 4.4dev on Windows 7, German. In addition, the content is shifted up, so that the first two lines of a multi-line cell content are hidden. I don’t find a report in Bugzilla. It would be nice, if you write a bug report.

Thank you for your report. I filed this issue to fdo 83099. Please leave a comment if you have some additional information.
