just updated Thunderbird to 38.2.0 and having now severe issues in forwarding, responding and writing emails (Thunderbird duplicates attachments, taking recipient of previous email as default for the next email, sometimes very slow inserting of names from the adressbook, hanging while typing, loss of "copy" and "cc" fields in the adress area).
I do not want to bother anyone here on the above because I do not think these problems are portable-specific.
But I would like to know if it is save to install a previous version over 38.2.0. Similar was requested by ChinaQD on June 17. John. T Haller replied how to find older versions, but he did not say explicit if it is save to follow the upgrade procedure just backwards. ( quote...just install a new [here:old] copy of Thunderbird Portable right over your old [here: new] one...unquote)
Thanks for your help!
