This is posted in my post as well, but now we have a half solution in two places:
Here's a half fix...there needs to be an update for option b:
A) if you use thunderbird (or firefox) that has this problem, do the following:
1) create thunderbird.bat
(right click, new, text document, then rename the file thunderbird.bat, you'll have to have your extentions showing)
2) add the following:
start C:\"Program Files (x86)\Mozilla Thunderbird\thunderbird.exe"
3) save
4) drag the batch file to od
5) right click on it and select dock entry properties
6) Change the icon, and run minimized (this keeps the black box from popping up)
Now thunderbird works as it should
If you use Thunderbird through your calendar link (like I do)
1) follow steps 1-3 above
2) right click the calendar and select dock entry properties
3) select the batch file as the link...or just change .exe to .bat
This allows thunderbird to work, but you will have a black box pop up for a very short period of time.
