[imp] IMP not in line with sidebar

[Yves Bilgeri]

Hi all,

I'm using on a fresh installed Server the Debian/Sarge Packages of 
Horde/IMP (Horde 3.0.4, IMP 4.02, Turba 2.0.2).

I'm not sure if i have had the problem already before i started to 
configure Horde or just after. Anyway the thing is when i'm in IMP, then 
the icons on the top are no more in one line with the sidebar. If i 
switch to Turba or the options then it looks OK. To clarify what i mean 
  i took these screenshots:

How can i correct the problem? In which file do i have to look?

Thanks in advance,
Yves
