ignoring my own advice i have been trying to test the new features.
In Biography v1.2.0 (by WilB) I made the next changes in menu.js
In line 1015
this.docTxt = doc.parentWindow.clipboardData.getData('text');
to
this.docTxt = utils.GetClipboardText();
And the menu paste text from clipboard works
In Library Tree v2.2.0 (by WilB) I made the next changes in search.js
In line 223
if (this.start != this.end) this.doc.parentWindow.clipboardData.setData('text', panel.search.txt.substring(this.start, this.end));
to
if (this.start != this.end) utils.SetClipboardText(text, panel.search.txt.substring(this.start, this.end));
In line 227
iif (this.start != this.end) this.doc.parentWindow.clipboardData.setData('text', panel.search.txt.substring(this.start, this.end)); // fall through
to
if (this.start != this.end) utils.SetClipboardText(text, panel.search.txt.substring(this.start, this.end)); // fall through
In line 290
text = this.doc.parentWindow.clipboardData.getData('text') || ''; // fall through
to
text = utils.GetClipboardText() || ''; // fall through
In line 387
his.paste = this.doc.parentWindow.clipboardData.getData('text') ? true : false;
to
this.paste = utils.GetClipboardText() ? true : false;
and the copy, cut and paste in the search field works
Of course changes was made by trial and error without coding knowledge so could be an aberration. Any help will be welcome
Thanks @marc2k3
