[Pydev-users] [Users] Eclipse frezes on code completion

[SourceForge.net <no...@so...>]

Hi,
When programming in Pydev in Eclipse, it keeps freezing every time it tries
to auto complete some code

Forexample when i type:

newString = "abc"

newString.something (newString"DOT"something) 

And then it frezes. And after a minute, if I am lucky it says "error connecting
to python process"

I get the following error from the eclipse error log:

!ENTRY org.python.pydev 4 4 2011-02-14 20:17:43.640
