Thunderbird Beta issue


I hope this is the right place to post about this issue.

Just installed Thunderbird Beta 112.0b3 (64-bit) a couple of days ago, getting the feel of this one and doing OK, but found an issue.

Buttons (screenshot supplied) are not working (not taking me anywhere) except for the calendar one, which works OK

Any feedback or instructions to correct this would be appreciated.

Regards, Jay
