Up until I upgraded to the beta circuit today, I was using TB V102.<something> I use a third-party desktop configuration program called WindowBlinds to set system colors and themes; it has always been able to set colors in Thunderbird with no issue... until I installed this beta version... Now, I simply get black text on bright white background, regardless of WindowBlinds theme. So I tried falling back on using Thunderbird settings... in Settings-> General -> Fonts & Colors, I have tried all combinations that I could think of, but *none* of them affect the Local Folders Folders and Messages display colors. Specifically, I have: > Enabled "Allow messages to use other fonts" > Under Colors window, have both set and cleared "Use system colors" If I SET "Use system colors", then all of the Settings tabs use the WindowBlinds colors, but neither Local Folders nor Calendar use them. If I CLEAR "Use system colors", then all of the Settings tabs use the fgnd/bgnd colors that I specify in the Colors dialog. I *really* want *all* of the windows to use my system colors, which were set by WindowBlinds... that's how it all worked before... that bright-white background on the message panes is Ghastly!!! I cannot bear to look at it...
