I'm having some problem with Umbrello as of rev 4.8, namely with the new code import wizard.

It was fine on 4.7.4, but I can't get the old version to show up in my Windows installer. The only repo that shows up is 4.8.

Here is the biggest problem, the code import dialog is so big that the OK button goes out of the screen, an I can't resize the window, so there's no way to click it. That's a show stopper.

And that's only one of the many wierd bug I found, can anybody help me get the old version?

While KDE 4.7.4 isn't available it seems, KDE 4.7.0 is. Provide the following url to it manually when asked, and it should offer you the chance to download it hopefully.

http://download.kde.org/Attic/4.7.0/win32/

Unfortunately it doesn't work. The installer tries to find a Stable folder, but fails.
