I receive emails that I want to store in folders under my account. I highlight the emails in the Inbox, right click the mouse, and either select the folder I used previously to store these emails, or, I use the "Move To" selection. When I select OK, the screen freezes. I am faced with two choices to get out of the problem, either "X" out to close the program, or, "Wait for the program". This last option never works, so I can only close T/Bird. When I reopen, the messages are still in the Inbox. I am using Windows 10 with T/Bird 45.1.0. I've notices in the forums that there is reference to Version 46.0, but when I check for updates, I am advised I have the latest version.
