TBird Version 78.1.0 - can't zoom in on an email text by using Ctrl + until first going to View-Zoom-Zoom In and clicking. Only after that has been done once can I then use the Ctrl + or Ctrl - to further zoom in or out. Additionally, I am now encountering freezes at various times while using TBird. This is something that I have never encountered in any prior version. I am continuing to get delays in sending messages and copying message to files. And, I am finding that occasionally when I run filters on folder the filters are not always working and the messages are not moved to the filter-designated location. Help will be appreciated.
