Doubleclick on titlebar or empty area opens file

[paciuli]

I don't know if any of you has encountered this before... I hope I can explain myself: when I open a pdf file (for example) and then go back to FC and try one of the following:

- double click on empty area (to go to parent folder)
- double click on titlebar (to restore/maximize window)

instead of the operation it's supposed to perform, it just re-opens that file. After some clicking around (or change of directory by other means) it goes back to the correct behaviour. Any clue? Thanks

EDIT: I also use CAFE to open files with custom applications, just noticed that it's ok with CAFE disabled. So I guess it must be a CAFE bug or maybe some non-perfect cooperatioon between the two programs...
