When I compose a reply, images in the initial message are sometimes replaced by an image from my hard drive (always the same one).
If I take more than a minute or two to compose a reply to an email that contains an image, the original image is sometimes replaced by an image it pulls from my hard drive files. It doesn't always happen, but when it does it is always the same image. I think it only happens when the image is pasted in to the original email, not if it is included as an attachment. When it happens, it replaces the original at the same size and proportions and this is the image that goes out to my email recipients. The only info I could find about this replacement image is this: mailbox:///C:/Users/Flywheelvt/AppData/Roaming/Thunderbird/Profiles/bd0utltz.Test/Mail/mail.flywheelvt.com/Drafts?number=186&header=quotebody&part=1.2&filename=efficiency-upgrades-calc.png
When I paste that into my PC search of my computer it finds no items that match it.
Any ideas?

take Thunderbird into offline mode. (click the two blue monitors in the bottom left corner of the screen.) Then FIle menu (Alt+F) and select compact folders. once the compact completes click the icon to go online again and see if the issue still appears.
Thanks. I tried that, but same result. It may only happen with .png files, not .jpg Also, it does the replacement when a reply window has been opened for awhile and then I try to save it as a draft.
Ok, so we try the next possible fix.
On the toolbar 
> Options > advanced> Network and disk space.
Turn off the automatic compaction.
Does it still do it?
I believe the automatic compaction is already off. Here's the screen shot of how it looks now, before I changed anything in Network and Disk Space.
This issue is almost always somehow related to compaction. So turn it on and increase the threshold to 100MB and see what happens.
Matt, I tried the compaction as you suggested, but still the same result. Any other suggestions? Do you need any more info?
