Nokia n800
I'm wondering, first of all, where all my internal memory is going. I recently flashed Diablo and freshly installed the applications I wanted. The storage details say I have 183.1MB in use, but the data tab shows I have 35.6mb of installed applications, and 807kb of other files. So what is taking up the other 146MB? I only added one email account and have no visible emails in the inbox.

Could it have something to do with the installed catalogs? Also, should I disable or delete any of these for system integrity? The list of catalogs is as follows.
Nokia Catalog
Nokia Catalog(3rd party software)
Nokia System Software Updates

I have MaemoMapper installed and 1.09 gig of maps on the external card. When I use the program, does it cache something somewhere else? Is that where all the memory is going?

And finally, I can't seem to use my internal 8gig card for saving or transferring anymore. The nokia reads files from it, but won't save or transfer anything new. (It's at 3.3GB in use) And if I remember correctly, it worked fine when I first flashed to Diablo, but once all the applications were installed, the problem started.

The last bit of information that may pertain to this, is, for a while after annotating a PDF in Xournal, an "Autosave" box kept flashing in the upper right corner of the nokia and didn't stop until I finally powered it down and took the battery out. (Even when powered down, it would still appear intermittently.) Is there a clipboard somewhere I can clear?

Thanks very much for any of your time. I appreciate the help.
