settings -- directory cache -- warning bad if no entry

[jgleicher]

In the settings box, on the Directory Cache node of the
tree, if you leave any of the boxes for the amout of
time to cache a directory blank and then press okay to
exit, you are presented with a warning, but it is
impossible to discern what the warning is about since
it is entirely blank. Leaving a field blank is a hard
stop, and you cannot exit the settings editor unless
you have a value in all of these boxes.

Suggestions:
Default to 0 when nothing is entered.
Display a warning message that details the problems.

Can you please try again with a recent version of FileZilla 2 and report back?

The error message is still blank if you try to use "OK" to exit and one of these fields is blank. Doesn't look like anything has changed.
(I found this on Windows XP, in case that's useful)

Development of FileZilla is completely focused on version 3 by now, so a cosmetical issue like this won't be fixed anymore.

You are welcome to test FileZilla 3 beta (which soon will hit the release candidate state).
