[Walter Lapchynski]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.9) Gecko/20100317 Lightning/1.0b1 Thunderbird/3.0.4

In HTML Compose, if you select Roman font and type characters, the cursor moves forward but the characters are not displayed. If characters are typed in any other font (and are, thus, displayed), then selected and changed to Roman font, the characters are still selected but not displayed. 

Reproducible: Always

Steps to Reproduce:
1. Compose message in HTML.
2. Select Roman font.
3. Type characters -> nothing is displayed but cursor moves forward.

OR

1. Compose message in HTML.
2. Type characters in non-Roman font.
3. Select characters.
4. Change to Roman font -> characters still selected but not displayed.
Actual Results:  
Characters aren't displayed.

Expected Results:  
Characters should be displayed.

Firefox bug <a href=https://bugzilla.mozilla.org/show_bug.cgi?id=512183>512183</a> may be related. However, this refers to specific font sizes, while this Thunderbird bug works for ANY font size.

Tried this on different machines in the building, same problem.
