[Pharo-users] Recent Pharo's seem to lose first keystroke when you swap to them to paste?

For a while I've noticed that every time I try and copy some text from a web browser or email and then paste it into pharo the first time it fails - and then thinking I didn't copy, I try it again and then realise that I have to paste twice - as the first one doesn't work. This didn't seem to do this in Pharo 9 (maybe 10) but its definitely the case in Pharo 11 and Pharo 12. This is on OSX (14.x) so I'm wondering if the same occurs in Windows or Linux or if its just my laptop? Its quite annoying and I'm wondering if it might be a side effect from the gradual UI changes in Pharo? I've looked in the issues tracker - but its a tricky thing to search for - and so I wanted to canvas experience and then will report it. Tim
