SVN+Eclipse: I have to checkout my own code after commit

Question

I often come upon a very strange behaviour when committing code to svn via eclipse.

For example I commit my code successfully at the end of my work day and then I turn my pc off.

The next day I check incoming changes and then I have to checkout my own code, I committed the day before.

This started happening after I got a new ThinkPad.

I have multiple Eclipse Workspaces which (I think) all seem to have this behaviour.

I think that my revision may stay after the commit or it somehow switches back to that old revision, but I can't really tell since this doesn't always happen.
