(Solved) How to (un)set glossy theme of Lazarus under windows

I have installed Lazarus 1.2.6 under Win 7 professional.
When I start it as normal Windows user Lazarus looks like programs on
a Mac with glossy buttons, see the attached screenshot.
When I start Lazarus with Windows admin privileges it looks like a
normal Windows program.

The problem is that I cannot figure out how to set or unset the theme.
One one hand I like the glossy style of the buttons but the compiled
program has the standard buttons that therefore on a slightly
different position than I designed. So I tried to unset the theme but
cannot find out where and how.

Does anybody have an idea?

In the project options, category "Application", there is a checkbox
"Use manifest file...". If this is checked you get a modern themed
application like in your screenshot, if not you get the un-themed old
Windows-95 style.

That doesn't change anything; my application appears always un-themed
while the designer has a theme.

While fiddling around, I found the solution: The main form of the
application has restrictions. There is a Font restriction for MacOS
and there the Size was set to 8. I reset this to 0 and then my
application always get a theme, no matter if I use manifest file in
the project options or not.

Hmm, Now I understand. it is not enough just to change the project
options and run the application, one must rebuild it before and then
compile to see the effect.

This can be marked SOLVED. I found the reason why Lazarus behaved
different on different PCs: The Windows screen settings must be set to
allow themes and use a modern theme.
Therefore the compiled applications look therefore different on
different Win 7 PCs.  No big problem but good to know and
to understand.
