Thunderbird Portable

I have a quick basic question. When I download install TBP, do I download it directly to my USB that I want to use or should I first download and install it to my harddrive, then install it onto my USB?

I need to select a date range of messages (several hundred) from main inbox to an archived inbox. How can I move so many msgs at one time from folder to folder?

I tried out Portable Thunderbird (via the full suite) installed to a Transcend TS16GSDHC6 16 GB SDHC Flash card. After installing the suite, I copied my existing mail stores to it, following the published instructions; copying the entire profile resulted in Thunderbird failing to start, so I backpedaled and copied the recommended minimum files. That worked, though I was missing a few UI customizations and some extensions.

A strange thing indeed: At one point the OK button at the bottom of the "Account Settings" dialog stopped working properly. I can still close the dialog by clicking Cancel, but OK doesn't work and hence no setting can be saved. Internet search turns up no solutions for me.

I´m trying to use signature at my portable e-mail and I don´t know how to do it. Someone can help me? Thank you!!!

I am running TB Portable V2.0.0.23. Since I don't have any other problems I have not updated to V3 yet.
This message comes up when I receive a message that takes the folder size over 100Mb. When I click O/K button, it continues to work. I didn't realize that TB had this limitation, or is there a setting that brings up this message?
Thanks

Update: Noticed I have an add-on called ShowFolderSize. One of it's options is to set a maximum folder size. The default is set to 100Mb. This is the problem. Just changed the setting. All O/K now.

I am able to open a message's full headers. Please give instructions for how to copy and paste the full headers so that I may forward such a message to to abuse @ (whatever domain name). Regular attempts to highlight, cut, and paste do not work for this purpose. I'll appreciate help with this issue.

First off, this will probably end up being more of a "Portable Apps" 
question, but the question is all within the domain of TB Portable... 
so I ask the question here.

I'm using TBPortable 2.0.0.24 (okay, I think I originally installed 
2.0.0.13, and it updated).  Yes, I've been using Portable TB for 
a long time. ;)

I just started a project where I needed a development profile.
So, I created 4 profiles --
o  I went to cmd.exe, 
o  I cd'd to [...\ThunderbirdPortable\App\thunderbird\]
o  I ran from command-line [thunderbird.exe -ProfileManager]

Hi

I can see a few posts on Word Wrap but these do not address my installation of Thunderbird 3.0.4 which falls over when the command used

Does anyone have any advice? AS non technical as poss please

TIA all

I am using a Canon scanner with Canon's CapturePerfect software. CapturePerfect always sends the scan to OutLook. I went to the Windows set defaults menu and Thunderbird portable is not on the list, so I can't select it. There's no option to add programs. The thumb drive is inserted and operating, but Windows doesn't recognize the portable apps on it's default list. Can anyone advise? Vista OS.
