since a few days my WeBuilder (10.2.0.121) freezes when I want to save a file. (Win Vista SP II, 32Bit, Intel QuadCore 2,4GHz, 3GB RAM)
When I try to save a file, WeBuiler freezes and doesn't respond for about a minute, then it comes back and has saved the file (but of course I can't work like this

I've tried several things:
- It doesn't matter if it's a huge or a short file.
- It doesn't matter if it's a html-, php- oder js-file
- It doesn't matter if there are many files opened in the editor or if it's the only one.
- It doesn't matter if there are many other programms running or if it's the only one
- It doesn't matter if I use STRG-S or the icon or file->save
I've tried to delete all settings and project-files and begin with a clean WeBuilder but it doesn't make a difference.
Has anybody the same problem or any idea what I could do to be able to work again?
Thx and greets
Christian
