[Qt-creator] Qt Creator response too slow

[Ladnar, Marc]

I'm using Qt4.5.0 and Creator latest Snapshot, in my case it does not 
take long for loading files. On startup of creator it takes a while ( 
about 40 secconds ) but it is really a huge project and for completion 
and this stuff there is much work to do on startup. I think it's normal 
in my case.
But I haven't tried Qt4.5.1 with this creator yet. Maybe I will do 
today.

Hi,
could anyone who experiences that problem fetch the creator sources, and 
a Qt 4.5.0 (note the 0 at the end, not 4.5.1), and compile creator with 
that qt version and try if the problem still persists?
I know it's much to ask for, but it would be tremendously helpful to 
know if that is a problem introduced in Qt or in QtCreator :) You can 
grab one of us on irc.freenode.net #qt-creator for help.

Regards, Eike
