When writing an email if I use the 'Insert>image' menu route the whole thunderbird app freezes (using win10, fully updated). However, if I manually copy and paste to insert an image via the clipboard, it seems to take OK. So have a workaround now, but worry the program route is failing. Am I missing a setting somewhere (I must say I have experienced glitches* since updating to the newest supernova version - 115 - and wishing I'd just stayed with the older previous version a while longer. *Other glitch is the system is endlessly demanding passwords for my hotmail accounts when checking email (not so for the yahoo or gmail accounts). Very frustrating and time consuming. Thanks for any advice Ken Dutton
