Class tree collapse after build

[Michael Gruetzner]

Hi,

I noticed, that the class tree automatically collapses after every  
build (active target/project). It seems that
this happens because the tree is updated after the build and the  
update causes the tree to collapse.

I find this very annoying. Is there a way to change this behaviour?  
I've searched through the options but
I couldn't find something useful.

Thank you in advance for any hints.

MfG
Michael
