Unable to write to home dir at times.

(Sorry if this is a dupe... I somehow got unsubscribed from the list
so I don't think my post made it to the list... my apologies if it did
and this is a dupe.)

Installed 7.04 of Ubuntu and love it.

However over the last couple days or so, I've been having and
interesting problem.   Every so often a program will have issues
writing to my home directory.   Never had this trouble up till now and
I've not messed with permissions on the home dir itself or the
sub-dirs under it.

Example, I was using gFTP to download some pictures from a friends FTP
server.  It created the sub-dirs fine, but couldn't write any of the
pictures to the directory.    Another example I just ran into is I was
attempting to install a new extension in Firefox and it couldn't.
Said it needed write permissions to chrome directory.  I checked all my
permissions and they are owned by my user id/group id.  And rebooting
didn't help.

I'm at a complete loss as to why this happens and why it happens intermittently.

Does anyone have any suggestions or anyone else seeing this issue?
It just started a few days ago.  During that time, I've done the
updates that the update mngr was telling me about but can't remember
what all was updated.

Thanks
