[Qt-creator] Qt Creator response too slow

[Boy Lenssen]

Hi,

I'm using Windows XP service pack 3. Language of OS is English. I've played around a bit with my 'regional and language options' in the control panel. The standards and formats are set to Dutch, on the 'Languages' tab pressing the details button, I've set the keyboard to Dutch (Netherlands)->US...

Not sure what info would be interesting for you further...
Willing to help, as I would like to use the latest Qt Creator...

Hm, thanks for trying out.
Could you elaborate a bit on your platform?
Are you using Linux? Which distribution? OS Language?
Thanks, Eike
