[horde] IMP Search loads a new IMP window

[Michael]

Hi,
Today I discovered a strange behaviour when using the Search in IMP.  
I'm not sure if it results from the latest updates via PEAR.

Generally the Search is still working if I'm not using the advanced  
search. But when using the "Advanced Search...", Horde loads a new IMP  
Inbox window which doubles the menu bar and the folder list. It looks  
quite strange and I cannot see any errors in the logs. To give a  
visible example I made a screen shot [1].

What I additionally discovered is, that when I want to view the S/MIME  
details [2], a new browser tab opens with the mailbox view [3].

What could be the reason for this problem?

Thanks,
Michael
