externals not respected until committed

Hi,

This happened sometime last week I guess, since I'm updating TSVN to use
the latest SVN trunk usually on weekends:

When I set an svn:external property, it isn't respected on an update
until I commit the property. Before, I could set or modify an external
property, then run update to get the changes, do my testing and *then*
commit the property change. Now I have to first commit the property
change. That's not good - I'd like to test such a change first before I
commit it.

Stefan
