Version: (using KDE 3.5.9) Installed from: SuSE RPMs Type AAA BBB so this entry will get into the history. Then get back to this edit box and type AAA suggestion list will appear. Hit esc. The suggestion list will be closed. Clear all the text. Now paste AAA the suggestion list appear. Hit esc. The suggestion list will be closed but also the pasted text will be cleared (bug).
Testing in 4.9.1: pasting does not bring up the completion list, so this is no longer valid. Pasting and pressing space brings up the completion list, but ESC only closes it but does not clear the text.
