OK, Update, my 4GB just locked up again last night. The one thing I had changed, is what locked it up. I changed the email to store attachments on the storage card. I put it in a reader and used the XP disk tools to discover that it was the email folder that was corrupt. Unfortunately, I had to reformat the device to get it to unselect "store attachments on storage card". I think it kept trying to look at it...the symptom was lacking up after 30 secs from every soft reset - until the card was popped out.

Lesson learned : Do not use anything that writes to the storage card regularly (Hubdog, Email Attachments, etc...).
Weather panel had been working funky before and I have also put it in main memory - it worked fine for a while (when installed on the 4gb card, but eventually could not read the config files on the storage card and would not work anymore).

I might try hubdog and use it as streaming only....might as well with free powervision...
